Listen. It really isn't "just" my dick talking.

So, my situation is this: If I don't make the correct decision, entire galaxy is fucked. Completely, and maybe forever. We just don't know if any other iteration can succeed. So, I really have to make the correct choice now.

On one hand, I have a religeous monk who follows 50 000 rules for life: Antidote to reason to such an extent, that I cannot at any moment rely on her doing the rational choice.She is a religeous fanatic. Her only loyality is to some book. Is she strong? Yes. But she's not broken strong.

And on the other hand, we have a genetical freak of nature with psycho powers so strong, she cannot even have sex without murdering. And if that wasn't enough, I save her life the moment I meet her, as well as solve her mommy issues in a single bullet. If that isn't a good way to buy loyality, what else can be?

I just cannot see, how the first one is the rational choice in any metric.
