I think it's a very valid strategy. First, it can help me a lot. Second, it can help them. Going around thinking I'm surrounded by people who don't care about me is probably the fastest way to misery and loneliness. On the contrary, if I think most people are dealing with many conflicts at the same time and trying their best, I feel so much connected to life itself.
Also, most conflict is back-and-forth attacks and counterattacks. You reject me, I ignore you, you call me names, I block you, etc. Instead, if you reject me, then I tell you it hurts you said that to me, and yet I imagine you've had a long day and are trying your best, it breaks the cycle.
It's not about caring it's about being aware of the ones who will abuse and exploit you with malice.
Life is not some break and forgive world, it's neutral if you bring a child in this world through rape and destruction, that is innately equal to consentual, kind and forgiving child rearing.
