Do some people deserve to die ? Any books about death penalty, or righteous killing ?

Ok to elaborate, i was talking with a christian and i told her that whether she accept it or not, god is a killer. And that the argument "God doesn't kill people, people are killing themselves by disobeying" is borderline dangerous when you think about it, like some kind of weird religious newspeak. 

And then she told me , ok god kills, but don't you think people deserve to die ? 

I said that i had no answer, and that i will think on the matter.

There are loads of books but your topic is a bit wide.

There are debates of the death penalty and the proper aim of punishment, there are discussions of self-defense, accounts of just war, discussions about the importance of intentions, accidents, luck, culpability, acts/omissions,  balancing competing outcomes, etc.
