The rest of what you said about bree I can't really argue with but find really strange to sympathise with a women basher. He didn't just hit her once when he found out about the affair it was established it was on going long before she arrived in the bay.
He had kidnapped bree basically rape her (she was to scared to say no to sleeping with him) and Jacob was about to kill Remi bree hit him in self defence once and tried to revive him after I find "killing the poor bloke" a huge stretch. It was clearly unintentional accident done in self defence saving someone else's life and as I said she didn't just run away she tried treating him afterwards
Yes cheating isn't right but in grand scheme of things it wasn't worst thing in this snerio she was in abusive relationship and his captive not like Levi or Brody who just cheated on wives who treated them well and they got bored when a shiny new toy came along
