You might not know what the Ten Commandments or עשרת הדברות are. The Ten Commandments are ten rules that G-d gave us when we got the Torah. If I could add an eleventh commandment to the Ten Commandments, I would add, “You shall not fight; no battles and no wars.” I want their to be peace in the world, so everyone can be happy and lead a good life. No one will be dying while fighting a war. Also, no one would have hatred towards another place, making them want to start a war. No fights could help eliminate no hatred. We could live in a place where peace is everywhere and we could all be happy. With this eleventh commandment, we can achieve that.
I believe that you are right that if we could eliminate hatred the world would be a better, safer, happier place!
