I have a more reasoned answer.
We are talking about chickens here, not about Donald Trump, President Bill Clinton, or even Pope Francis. About the only major things that chickens and humans have in common are warm blood and a spine, well chickens have sort of a spine. So to hold a chicken to some arbitrary human behavioral standard is just wrong.
Five week old biddies in the late Spring are fully independent of mama. At least the biddies are as long as they can reach a high enough roost. And even then no chicken is 100% safe at night, especially if it is roosting out in the open or in-other-words …..smack dab in the middle of the varmints' larder. If normal chicken behavior is so shocking to you then IMHO you will be happier if you were hen less as well as rooster less.
I think that you are correct in your latest judgment.
