Inappropriate TV

I am really struggling with my kids dad and his lack of thought. He barely spends any time with our kids as it is, preferring to work all the hours he can, even though I still pay 50/50 as a sahm and he often doesn't pay bills he is supposed to. Anyway that's a separate issue. He is rarely up with me and our two children (1 and 3) in the morning but today he was. Whilst I had a 2 minute shower in the room next to where they were playing (and the kids often come in and out to me anyway). Their dad put on a nature show to watch, and when I came in and between doing the breakfast and getting clothes ready it looked fine but then he gets up to leave and says the daddy lion is about to kill the baby lions. Walks out like its nothing. I search for the remote to turn it over not wanting my small children to see that and he came in all angry asking why I'm turning it off. I say it will scare and could traumatise them and he replies well you traumatise them. He's actually done this kind of thing before, cannot accept his wrong choice and instead turns it childishly to me in any way he can. He snatched the remote determined to have his way but turned it to monster trucks instead. He was verbally abusive to me saying I'm not perfect, I hadn't even blamed him tbf just wanted to turn the TV off before the bloodshed started. And then said me arguining with him was worse than what they would have seen. I didn't even want to discuss it with him,I just wanted it off to protect my children. I didn't say anything after that just got on with caring for my kids. He came in as he left gave me a one sided hug and said he was sorry he left the bathroom sink dirty. And then left...this man is insane???
