In my faith, there are three cardinal sins: lust of the flesh, the lust of the eyes, and pride of life. All three open doors to all selfish activity which leads to hate, yet never satisfies. I say hate is a result of sin in one's personal life. It's an easy thing to run with hate toward our fellow man and actually enjoy the process of degrading another life.
Lust of the flesh is an unholy desire of the physical or what we do such as food, drink, chemicals, body manipulation, or sex. The supreme goal is what feels good to the individual without regard to consequence to self or others.
Lust of the eyes involves greed or what we want to have and desire of the unearned and what one has no right to own. Stealing, cheating, embezzlement, paying unjust wages, swindling.
And the pride of life or what we may want to be such as personal advancement at the expense of others or imitate another lifestyle without counting the cost, or selfish need for vengeance. A lot of people tend to fall in extreme debt through the pride of life by trying to compete with their associates.
When we rush to hate without taking the time to research, seek truth with all our heart, mind, soul, and strength, we invite sin into our lives. We read of small children taking their own lives because their world has become too hard, people killing others of another race/religion, or adult men taking little girls as brides, or children give their lives to hate groups who want to kill, mothers who kill their own children, rapist, murder, bombing, arson,...the list is endless and all the crueler.
I say just as sin is so easy, the holy life is easy. Our Creator loves us, desires His best for us in every matter and will not allow us to suffer more that we can manage. God is our perfect loving Creator.
Yes, the Ruler of the Universe is the Creator and Loves Us. His Love Endures Forever.
We can love one another. It's just that easy.
