Things affect us. What we do as a result is up to us. So while you should be understanding of others, and how their trauma may have affected them, it also doesn’t give them an excuse to do the same. It’s a hard balance, being understanding vs not excusing them.
The Bible isn’t horrific. Don’t let others tell you it is just because they don’t like it. There are a lot of historical stories in the Bible about people. People are sinful, and do bad things. Just because something is in the Bible, doesn’t mean God approved of it happening, and that we are to mimic it.
Yes, there are horrifying stories, I guess I read your comment differently than you meant it.
