I hate the 'he had a family' line. Does that mean killing single men and women or people who never married makes it somehow OK? Like if Charlie Kirk was both single and celibate and said he was 'married to his principles and mission' (with no indication of being a closeted gay man or asexual) would that have made his murder more acceptable?

Countless evil people were married and had kids. Stalin was known to be a doting father. Saddam was also known by his children as a very kind and affectionate father. Roy de Mayo, one of the most infamous mafia hitmen, had a family and his family life was so quiet and unremarkable that his children had absolutely no idea whatsoever that their father killed people for a living (and his son had a nervous breakdown when he saw the movie Murder Machine in the early 90s, which was about his then dead dad).
