Not an AIBU I know, I’m sure we all are. This was a misogynistic man who identified as an ‘incel’. I’ve never heard of this phrase, but this man”s attitudes to women are common enough. Ok he hated his mum, not unusual, but no reason to kill her. But why kill the others, especially the child? This is all so sad and shocking and it seems that violence against women is becoming so prevalent again.
