For the whole "not killing Luka" point, it's  clear succubi are not the most constant and reliable bunch, and have tendency to live for the moment.

Add to that the pride in strength present in most monsters, and it's clear they won't be careful with anyone they consider weaker, even if he can be vital to their plan.

The Lilith sisters are paragons of this mindset.
