the video basically both agrees with you, and at the same time makes a compelling argument that all the people killing us right now are sad pathetic losers whose daddies never loved them, and they see no avenue to a better tomorrow so they do… this

That's basically why I've moved from a "f them , they get what they deserve" to trying to establish dialogue that offers a path to redemption/atonement. If the person demonstrates no good faith and continues to attack, boundaries must be set and enforced. When good faith is demonstrated, we try again. If they revert to abhorrent behavior, we set former and more extensive boundaries. If they are straight up belligerent/dangerous, we segregate and rehabilitate/re-educate humanely, and attempt reintegration. Capitalism is not the system for that. It's time to try socialism.
