What about shooting a woman in the head and a villian?
What about murdering a whole crew of people ?

Yes they are doing stuff to desensitize the violence but Violence is around. No question MCU will be able to show as much violence as a Fox movie. Violence in movies is easy. The harder thing is nudity and sexuaity you will never see hugh jackman butt in a disney movie, and something like say lesbian sex scene would be avoided as well. Also they won't drop a F-bomb in Disney(but Samuel L Jackson almost F-bomb had the same effect so who cares) .Straight violence is no problem the rules are the same as fox don't show blood and cut away from the most violence parts and then come back let the audience see the aftermath. Disney movies will show mature content who gives two craps if a Fox scene is a tiny bit more brutal.
Thanos stab a man with sword ,snapped Loki neck, Threw Gamora to her death off cliff, Was shown ordering genocide of people but we are hear having discussion if Disney can do mature content this convo makes no sense.
