Why is murder wrong if Many Worlds Interpretation of Quantum Mechanics (the Quantum Immortality) is true?

[brimstoneSalad]

You said that suicide is not a good idea because, if Quantum Immortality is true (and we cannot prove that it isn't), suiciders simply wake up in some parallel universe, but with high probability of being paralyzed. But doesn't the same apply to euthanised people then? Don't euthanised people, if Quantum Immortality is true, wake up in some parallel universe, but with high probability of being paralyzed.

Failure of medical euthanasia would be less common, and less likely to result in paralysis.

How do you know that?

Because chemically induced heart stopping isn't going to break your neck or selectively damage a specific region of your brain leaving the rest in tact like a bullet may.
You might get some brain damage generally, but that would also most likely affect your consciousness generally, such as putting you into a coma or resulting in retardation. Also, if it's administered by a doctor, they're going to just keep trying until they get it right. You'd be dealing with a vanishingly small portion of universes (astronomically small), compared to perhaps a 3% success rate for suicides generally if statistics like these are to be believed:

"1.1m actually attempted suicide, but only just over 33,000 succeeded."

It's dubious so I'm not going to cite the source with a link, but the point being there is reason to believe most suicide attempts fail. Guns and jumping from tall buildings are probably more reliable, but still a toss up. People have survived falling out of planes and being shot in the head before.

Even if you came up with a suicide method that had a one in a million survival rate, you're still in trouble versus medical assist which is going to have one in a googolplex or less.

I think you have more certainty than is justified from math.

I disagree, and a growing contingent of physicists consider MWI trivially true according to the most straight forward interpretation of the math (some of them question whether the other worlds are "real" as Hawking did with no explanation likely due to spiritual beliefs). The alterative is claims of wave function collapse (e.g. Copenhagen), which is an additional assumption. Hidden variable has been pretty well debunked (which is what we can expect with neo-hidden variable interpretations, quantum foam, whatever).
Occam's razor would have us err on the side of the MW interpretation in philosophy. We don't need to be any more confident to assume it as true than to know it requires no additional assumptions. It is the assumption of collapse that needs evidence, not its default rejection.

We know of four dimensions extended beyond known measurement from our experience, curvature effects determine that there would likely be a fifth extended dimension.

You lost me there. I don't know what you're reading but I don't think we know any such thing.
I'm also not sure why you think that's relevant. The Many Worlds may be called "dimensions" in the colloquial sense, but they're not classical dimensions of space a la the claims of sensational yellow journalism.

There are three known dimensions of space and one of time. Yes, space-time has "curvature", but I don't think it does what you think it does, although maybe you could call that topology a fifth dimension in some sense. It wouldn't surprise me, but it seems more of a semantic issue.

Other dimensions that are figured as explanation of string theory or M theory circle around tightly at a subatomic measurement, they would not account for alternate realities.

Slight quibble, but relevant to the credibility of these ideas: these are not theories, they are models. Theories have empirical evidence or viable tests for such evidence that exclude alternatives.
It's understandably confusing when "string theory" has theory in the name, but isn't one.

In the same way you can not test MWI like that to exclude, for instance, Copenhagen. MWI is preferred by Occam's razor, not strength of empirical evidence for a theory. It's what we get when we don't assume collapse, simple as that.

String theory, or anything else, doesn't have to account for MWI. MWI is an assumption that comes from the mathematics of wave forms, nothing more.

That fifth dimension does not give us indication that there are alternate realities of us. We do not know what would be out there.

One would not expect it to. The other worlds in MWI are not "out there" in the way you seem to be suggesting... they're parallel diverged realities that are as far as we can know or expect functionally inaccessible.

@brimstoneSalad You have piqued my interest, any relevant videos/documentaries or reading related to the MWI you would suggest to a layman?

I would just get some introductory stuff on quantum mechanics. I don't think there's anything useful on MWI specifically that would be on a layman level, because there's not very much to say about that specifically. Most texts will include a chapter or so on MWI. QM in general has limited impact on philosophy. Mostly just useful in disproving an assortment of god concepts.

OK, well, what if I try to suffocate myself in nitrogen? What bad happens if I fail? Or, much simpler, to drown in a river. What bad happens if I fail?

I want my father dead. So, what is wrong with me making him dead for me? I am not making him dead for himself.

I think that murder isn't wrong because you because you did something wrong, it's because the victim doesn't want it to happen. And we still aren't sure about anything quantum, and does it really matter? Murder is murder, and it should (usually) be punished.

For one, you could die.
