I’m angry at my parents and I am sorry

From ages 7-13 I was assaulted by my neighbor. He had a son my friend 2 years younger than me and he assaulted him too along with his niece who is about 4 years younger than me. Everything you could imagine that happened happened. Is it wrong that I feel as though I have misplaced anger towards my parents.. there were so many warning signs that I don’t know how were missed. Constant porn watching when I was like 9-10, in the 4th grade a couple of my friends from school spent the night and we were touching each others genitals, which one of my friends mom found out and told my parents. I just don’t understand, how they could have missed these. I don’t blame them but I’m so angry. I struggle now with thoughts of hurting kids the way I was. And every so often those thoughts come back and I have to completely shut myself out from the world. I watch porn like 7 times a day.. I just am useless. I know I shouldn’t be mad at them. But I am
