The guy decided to kill his girlfriend after she posed topless.
While I don’t excuse that murder, I understand it. Sex inflames people. When he saw his girl taking her top off for a photo shoot, he started crying and decided he would kill her that night.
I had a girlfriend who, a few weeks after we broke up, decided to pose nude for public display. It ripped me up. I never thought of doing her harm, but it hurt me.
If a man or woman come home and find their spouse in bed with someone else, well, many people get killed in that situation.
