Palpatine

I do agree that Palpatine wouldn't want to exterminate everything like Davros but I do feel he comes off as more evil than Davros and kills plenty enough (probably quadrillions minimum with various Death Star incarnations alone) that if he felt total destruction of as many as the Daleks try to exterminate was the way to acheive his goals he'd do so without a second thought. If you told me there exists a hypothetical Dr Who storyline where Davros is somehow convinced that extermination isn't the answer and that there is a good use for non-Dalek, I would believe it.

Wikipedia (in an episode I have not seen yet as Im still in Matt Smith episodes, so feel free to correct context here) also supports this theory.

The Doctor then discovers the Daleks have a concept of mercy and are allowed to have the word in their vocabulary when he encounters Clara, having disguised herself in a Dalek's robotic chassis. The Doctor and Clara escape, the former having an epiphany as to how Davros somehow put a sliver of compassion into the Daleks

Davros is basically a Nazi (where any non Dalek should be genocided) in a way but I do think he there is potential for him to be reasoned with. He shows some human qualities and has a weird sense of honor about him too imo-- I don't feel he would betray a close ally for example where again Palpatine would without a second thought.
