Do you think schools should start a new program like anger management as a required course?

I just read an article about the killer of Aiden Laos being found. He is a 24 year old young man who said he got angry when he got flipped off by Aidens mom and responded by shooting at her. At 24 he has altered his life severely and taken a young life because he wasn’t thinking about the outcome. Just his anger. I think people are getting so much worse at controlling themselves.

I’m angry and have a gun and somehow that is supposed to make things better. Only what it really does is totally destroy your life. Easy to blame gun ownership but the reality is people have lost common sense and the ability to think rationally.
I call the course anger management but it needs to be that combined with instruction on how not to be a total idiot and ruin your life and those around you.
I think it needs to start in 1’st grade. Teach children early on how to resolve conflicts before it becomes something they can’t take back.
So what do you think? Will it work, or just a pie in the sky idea?
Do you think something else is missing that could add to such a program? Or is mankinds propensity for violence to great to overcome?
