what makes a killer?

When we see terrible headlines like "Man Gets Life for Family Murder" or "Mall Shooting Kills Innocent People," it's easy to just think of the person as "sick" or "evil." And yes, what they did is awful. But it's worth asking: what makes someone like that? People aren't usually born with severe mental issues or disorders that make them commit such acts. Usually, something big happens, or a lot of bad things pile up, that changes them. The person we call a "killer" wasn't always that way. Something, or someone, made them into that. Maybe they had an abusive parent, a terrible breakup, or even a really sad past themselves. It's often true, though we don't always think about it, that many people who do terrible things have also lost someone very important to them. But society usually only looks at the person after they've done something terrible, not before. They weren't always "the killer." Sometimes, they even knew their victim, and sometimes, losing someone they loved tragically pushes them to become the very person they now are. This doesn't excuse what they did at all. But before we just label someone as purely evil, maybe we should try to understand the complicated life experiences that might have led them to such a dark place.
