The concept of good and evil is actually very limiting and tends to raise people with twisted worldviews. Most intelligent people learn that morality is complex, reality is not black and white, and to wish harm upon others to ensure personal bliss is rather sociopathic and fucked up.

Christianity faces a major foundational dissonance. Early tribalist (in group, out group thinking) values that have to coexist with radical empathic universalism. They usually ignore the development of Jewish traditions, and it took priests centuries of dissertation to mesh both views together. But they are incompatible. To believe in clearcut good and evil, and also things like a reward heaven (an idea also eradicated in most Jewish tradition). One must learn to suspend empathy for the fellow human being. To be happy while knowing others are harshly suffering (aka "they deserve it"). To think that one's own cruelty will be forgiven just by saying a magical incantation is also fucked up.

Now, the solution given to it is not widely accepted, and is the source of schisms in different Christian cults. Jesus's message is that of universal forgiveness with radical empathy. The abolition of heaven and hell. But many intermediate concepts had to be inserted to make it make sense with organized religion. Like sin forgivenes through repentance, second coming prophecies to delay the forgivines, apocalyptic prophecies to delay the abolition of hell and other exceptionalist interpretations.

Anyways, I started rambling, but Christianity is incapable to be internally consistent as it is. And some dogmatic views require people to be actively assholes by definition.
