The problem of evil

They say that man's greatest talent is adaptability.
That's why it can adapt everywhere and everything, so that being able to live on Mars can evolve from a dream to theory and then to practice. it's the sciences. While removing some living things from their environment costs their lives, this is not a problem for humans.
Is it just environmental factors, but this habit/adaptation?
not.
People get used to everything, evil loses its meaning for those who get used to evil, so bad people can stay bad... goodness is like that. Staying well is the result of a person getting used to it.
