“Maybe he should’ve ended the relationship with said woman instead of brutally killing a young man.”
While I don’t entirely understand your written response, I believe we are on the same page: The kid did not deserve to die but banging another man’s wife was a bad decision on his part and cost him his life.
Very sad chain of events, but then again, the Good Lord made it very clear with the 6th Commandment: Thou shall not commit adultery (a.k.a.: Don’t bang another man’s wife).
Kid made the wrong choice dice and died.
Meaning the cop had a choice (if any of this is true) to dump his girlfriend for cheating on him or stay. He chose instead to beat a young man to death who may not have realized she was in another relationship (with the cop). Not a very smart cop, who obviously believed himself above the law.
