Funnily enough, Mercurius pretty much became friends with the only being that could kill him. This friend being Reinhard. In the final route they fight eachother anyway, which makes Reinhard pretty much laugh with joy, as to be expected. Lol. I think it is either Marie's route or Rea's.

Ren's apoptosis, Shirou, is also his friend. Although they did almost fight to the death a month before the story actually began. I don't know why as of yet though. As for how he looks? Well, like this. And apoptosis doesn't really have anything to do with morality but a contradiction in the God's desire. He is pretty much the badass normal of the 'verse until he attains Yetzirah.

So, no, your apoptosis won't by default become your enemy. But more often than not it will most likely happen. And the 'verse also uses hinduism and buddhist concepts like atman. There is also a mix of chinese in it, as evident by the term Taikyoku which means 'Supreme Ultimate'.
