Ofcourse -“Unfortunately some Mechanchim are dangerously impulsive/explosive/hurtful.”
This statement applies to every human being, not just Mechachim. In the time of Chazal you could expect a Rebbe to be a Malach -therefore the Torah requests to look for such people. In our day and age, the Rebbeyim/principals who are Malachim are far and few inbetween.
Every person has to work on themselves and not worry about the next guy. This is very hard and the biggest Nisoyon of our generation. I’ve had some very bad things done to me and I tried to get Justice, but I didn’t succeed. Real Justice will be in the next world!
