My friend and colleague just had a fight! My colleague hit my friend and his mouth was bleeding! I went to Indiana, and my friend was beaten. I grabbed him when he tried to fight back.

Although it is not a legal question, I still want to answer you:

1, your behavior is correct, don't regret it.

2. If you hadn't hugged your friend, if your friend had slightly injured him at once, he would have done it already, so you are right and a true friend!

3. If you help a friend fight together, it seems like friendship, but it is likely to have consequences that you will regret!

If your friends blame you and your colleagues laugh at you, you can only say that they are not as mature as you!

You should be happy instead of blaming yourself.
