you shouldn't do anything
No, you should never tell an abuser you love them and if you think you love them then you need psychological counseling because abusing a person is not about love. You don't hurt the ones you love! Get out of this relationship while you still can!
You should not wish revenge against an abuser, this will only make your abuser furious and cause them to harm you more than they already have. To stop an abuser you need to talk to the authorities and if you are a teenager or younger person that is being abuse you need to talk to a trusted adult for help.
An abuser or a bully.
That's like asking "Should a child abuser be allowed to keep custody of their child?"
Yes and no it all depends on the person
Reasoning with an abuser is not something the abused person should probably try. Most abusers are very good at manipulation. If you try to discuss it with them, you may be disappointed and become more hurt and angry. If they are an abuser, they already know it, but do not expect them to admit it.Rather then reason with them, you should talk to someone that you trust about it. It might be hard to admit to someone that you are being abused, but it is better to face your fear by reaching out to someone then continuing to be abused.
Have the abuser arrested.
Kidnapper, child abuser
Yes. It harms the family and friends of the drug abuser. Also, if anyone looks up to that person, they could do the same thing.
A person who abuses an elder person who has no control and can not defend themselves is of low character and yes, if there are marks on the victim and the abuse has been reported to police the abuser can and should go to jail
To stop abusers, they should be held accountable for their actions. If someone reports the abuse to the police, the person may stop their abuse.
you are an abuser if you demean the other person (tell them they are worthless, stupid, lame, etc). whatever makes the person feel small and "less than" is abuse
