Fortunately, I do know several couples with years of marriage and genuine love, that doesn't mean they don't have their problems, but they are overcoming them, on the other hand, what you mention of people who can approach us in a selfless way and truly willing to support us when we are in trouble in the street is a great show of empathy that I particularly have received gratefully.

On the other hand, I agree with you that hatred is a feeling that consumes the one who feels it, so it is better to put it aside and wait for the actions of evil people to catch up with them as you yourself have mentioned.
