God allows evil, such as serial killers, to exist because without it we would never know the full range of the human moral compass. If everyone was good and near-perfect on earth, then we would have nothing to go on. Think about if we removed all evil people that'd harmed others, what would we be left with? People that accidently said something rude? People that accidently crashed their car and hurt someone? Petty criminals that commit nonphysical crimes? These are not examples of evil people, they're good people that had an accident, and/or desperate people. They would not teach us why we need to be good. The only way you can learn that is by seeing the damage that a truly evil individual can cause.
