In that case I don't think MWI says anything we didn't already know: specifically that 'stuff happens' outside of our control, which is something which we have to deal with even in non-quantum lines of thought. Trying to make choices different when acknowledging that MWI is true probably will result in no utility gain at all, since saying that x number of future worlds out of the total will result in some undesirable state, is the same as saying, under copenhagen, the chances it will happen to you is x out-of total. And that lack of meaningfull difference should be a clue as to MWI's falshood.

In the end the only way to guide our actions is to abide by rational ethics, and seek to improve those.
