I can find you both biblical and Koranic verses to apparently condone or justify several bad things.
The question is whether there are people reading them and actually doing the bad things. And of course, most of the bad stuff you'll be citing is in the old testament, which immediately falls to the doctrine of the "New Covenant".
More fundamentally, there are very, very few Christian churches, even the really crazy ones, which believe the bible to be divinely inspired anyway. The furthest they will go is that in the nuttier fringes of evangelicalism they have "red letter" bibles in which the reported words of Jesus are given an extra boost of credibility by red ink. But that rather undermines the "bad things" claim, because it's the old testament where the bad stuff resides, and obviously there's no red ink in there, so the bad stuff is all implicitly less reliable.
(( Some of the very nutty churches start into things like regarding the King James bible as divinely inspired in that form, or even nuttier dismissing the old testament on the grounds that it's Jewish, but we're really in the fringes by this point. ))
That's why Christians aren't too bothered about, say, the burning of bibles. Not divinely inspired. No agreed contents. Even the basic contents not standardised until the Council of Trent. Doesn't form the supreme basis, or even the basis, for doctrine (Catholicism is reason, scripture and tradition, for example).
