Surely there's a segment of the population with similar personality traits predominant to police officers that don't become police officers. One would think they'd also have similar incident of domestic violence if this were a personality trait?

Personally, I would have no interest in dealing with the horrible things people do to one another, on a regular basis, as part of my job. No thanks. Reading the news is bad enough, I wouldn't want to live it.

No one is claiming it's a personality trait, though that absolutely could be a part of it. More likely, it's because police officers can act with impunity in pretty much every scenario. Add in a high-pressure job, and you've got a recipe for abuse.

Nevermind the fact that steroid abuse is common in the police. The BMJ has a lovely factsheet on anabolic steroid abuse: https://bestpractice.bmj.com/topics/en-us/987

Risk factors: "employment as nightclub bouncer, professional male dancer, professional wrestler, or law enforcement officer"

Funny enough, casual criminals fit that picture quite well. That would explain why they are attracted to "the horrible things people do to one another, on a regular basis" - to a non-trivial extent, they share the character traits of the people who do these things in the first place.
