Suicide means that there is too much pressure recently, and I want to get rid of the bondage of pressure and find another way. Killing people is to show their strong and violent side, so it just reflects their recent physical weakness, such as fatigue and illness. I am exhausted. The rope here represents possessiveness and control, which means you want to possess and control your girlfriend and make him yours. It seems that you still love her.
Killing people thinking of breaking the law shows that although you want to vent your anger, you are still rational. You can think of taking responsibility after killing, which shows that you can control your desire and anger, and understand that breaking up is a fact and cannot be redeemed, so it also shows that your mind is mature.
