They don’t care what kind of wasteland they create around them as long as Allah is pleased. They don’t care about dying themselves or killing other people as they will enjoy 99 virgins in heaven. In that sense they don’t. It’s like medieval theology on steroids.
Well, sometimes the medievals got a bad rap as being even worse than they were.
A proper focus on eternity will cause it to be mirrored, however imperfectly, on earth.
Allah is not Jehovah. Get that perfectly straight. One is evil, one is not.
