You're decisions aren't random! If you decide to do something then the vast majority of other selves you have will decide the same thing. When you do good you do indeed do good in all universes branching from this one.

(But what if what I just said wasn't the case? Would you let your sense of ethics override the physical evidence? Look at the causal history of your morality: it comes from evolution. Do you think that if MW was true then evolution would be forced to happen differently, in order to give you different morals?

This is a good question, but I think it's important to understand that it's a good question. Evidence from the physical sciences doesn't have some fixed priority over other kinds of evidence. One could argue that its an unusually good source of evidence, of course, but I'm not sure how to make the comparison in this case.
