Why must you hate so much?

I just dont understand why so many people in this world have so much hate for them selves and for others. Life is to short for each human to have regrets or hold grudges. So open your heart up and forgive the ones who have hurt you and apoligize for the hurt you have given. You can always forgive you dont have to forget but you can let it go. Everyone deserves to be loved,
even the ones with hate in their hearts. So please make tht phone call or drive that extra mile to make peace with that one you are having problems with. If it is something you feel should not be forgave let God handle it, but you forgive. You do not have to be friend with that certain person that has given you hate, but just make peace let them know you do care and love them no matter what. So when life does come to its end like it will do, you can RIP knowing you had no hate on your heart and God will love you even more for this decision.
