what do u need to destroy someone?

Sorry I fully disagree your thoughts. Friendship is a pure relationship and one should not use it as a method of taking revenge or destroying some one. Their can be other ways or hurting or taking revenge but friendship should not be used as a medium of doing so. Once you make some one a friend, it very difficult to hurt them. Friendship is a feeling which can only be felt from our hearts.

If you want to destroy a person thenthe greatest weapon is ignorance, if you start ignoring that person then you are destroying him/her little byt little until he/she feels very bad about it.

I think what you say is mostly true. My best friend has made me feel the worst. I couldn't believe she is my friend based on some of the things she'll say to me. It's sad that there are people who would befriend you only to hurt you but I guess we have to be careful and take care of ourselves

So I can conclude love is the most dangerous weapon?

If you mean destroying a person's spirit then the best way to is to gain trust and love and then break that trust. One of the greatest pain is when the one you love the most cheats on you. It can leave a very deep scar on the pysche.

i think the best way to destroy someone is try your best to be better than him in every aspect. He will become very frustrated just by looking at you. At the same time, you improve yourself, one stone two birds.
