No. Hurting a person will not make your anger go away nor is it in any way an acceptable thing to do.
if the person is purposely hurting you then yes if there just annoying you then no.
you don't it's better to tell them in person
hurting someone intentionally, knowing that it's hurting them.
yes, if someone is stealin from you or hurting you it is ok to use self defense.
just tell him that there is someone ells in your life and that he's not that person
Yes it is.
Love is a precious thing, if you have found it with someone and that person loves you back...don't let anyone get in between you. If love is ment to be, it will be.
The term for a person who derives pleasure from hurting others is a sadist.
You stop them and tell them that what they are doing is wrong. If there a hurting someone of color then you should lead that person away and stop the fight.
If the person is in danger from someone else, a danger to themselves (self-harm, suicide), a danger of hurting someone else, or if the person is going to commit or has committed a serious crime (sexual abuse, murder, etc).
I suppose it depends on the people in question. Ask yourself these questions: Which person would be better for you in the long run? Is Person #2 worth you hurting Person #1? Who do you think would treat you better/has been treating you better?
