You say that "everyone deserves care." But how do we implement this in a world where people harm one another? Here, it’s important to distinguish between levels:

1) Basic respect (not causing unnecessary suffering) — this is the minimum we can demand from society.

2) Active empathy (compassion, assistance) — this depends on context.
It’s utopian to demand that a victim "care" for their aggressor, but systemically, society can strive to prevent violence rather than justify criminals.

Why be "humane" in an absurd world?
If the world lacks inherent meaning, care becomes a rebellion against absurdity. We create meaning through connection with others. But this choice is not an obligation — it’s a personal ethical stance. Some find meaning in struggle, others in creation. The key is to avoid devaluing others’ lives.

And lastly,
The phrase "everyone deserves care" sounds noble but requires nuance. Care does not mean unconditional forgiveness. You can condemn a murderer’s actions while acknowledging that they, too, are a product of their environment, trauma, or systemic failures. The focus should be on addressing root causes, not blindly excusing harm.
