Two major schools of thought:

We should help everyone, even if it means "bad people" can take some from the system.

We should not help anyone but a tiny fraction of people so that no "bad people" can benefit from the system.

Personally, I don't really favor making the world that much worse to avoid some spoilage. We can do better than hurting a lot of people so we get the "bad" ones, who in my view are responding to material conditions, neurology, and history.

I don't know that any particular person said it, but I agree with the notion that the first sign of civilization was a human corpse, with a femur that had been broken, and then healed. A human with a broken leg is pretty screwed on their own. Someone had to help that person get food and water long enough for it to heal. Civilization is when we help each other fulfill our needs, and that's beautiful.
