Violence is indeed a trigger for many of us....for very good reason.
Condemning someone is one thing; encouraging them to seek help is another. Perhaps that encouragement *will* lead to even a small effort to change.
Until presented with reasons to change, it's doubtful anyone will...

Making an effort does not mean their acts of violence need be tolerated, and this should be addressed directly and without malice. I believe it has been in this thread.
People have to be held accountable for their actions.

My own belief is there are always two sides to every story.
Not three or four or how ever many times the story changes to suit the person or justify their actions.
There most likely is more to this situation than was posted; response was made to the violence this person exhibited during one event. To remain silent about it does this person no favors. Suggesting professional help was made several times, along with hopes they will find more peace.

Several posters have given encouragement and support about seeking help for this obvious lack of impulse control.
Denying they have a problem and blaming someone else are things that should be covered in therapy if there is honest dialogue...and that was also encouraged.

Jmo, but there was more of a "calling him on his actions" than anything else...
