A question the movie does't answer?

In the movie Prot makes the statement "I wanna tell you something Mark, something you do not yet know, that we K-PAXians have been around long enough to have discovered. The universe will expand, then it will collapse back on itself, then will expand again. It will repeat this process forever. What you don't you know is that when the universe expands again, everything will be as it is now. Whatever mistakes you make this time around, you will live through on your next pass. Every mistake you make, you will live through again, & again, forever. So my advice to you is to get it right this time around. Because this time is all you have."

I agree at first this seems to be saying something about trying to do the right thing the first time you have the chance to make the decision to do so. Or similarly, there is no time like the present to get it right.

However, he doesn't give both options of getting it right or wrong the same weight. I'll try to explain. If one doesn't make the mistake the first go around, is it impossible to make the mistake the next time around? According to Prot, are we not really locked into the first time the decision was made, sometime in the distant past?

If not, why can't we 'get it right' and not make the same mistake the next go around? And if we are locked into whatever was decided the first go around, why worry about what we decide? Wouldn't we always just make the same decisions?

I think his logic is a little flawed. Any thoughts?
