Can we rephrase that so as to avoid Ship of Theseus issues?

Which future do you prefer? The future which contains a being which is very similar to the one you are presently, or the future which contains a being which is very similar to what you are presently +/- some specific pieces?

If you answered the latter, what is the content of "+/- some specific pieces"? Why? And which changes would you be sorry to make, even if you make them anyway due to the positive consequences of making those changes? (for example, OPs pedophile might delete his pedophilia simply for the social consequences, but might rather have positive social consequences and not alter himself)
