I sympathize with this view, but I think many people's biggest contributions to humanity are not through care for others. Take Donald Knuth, just off the top of my head. I've seen people close to him write glowingly of his personal qualities, but I would argue his contribution to humanity is overwhelmingly through his work, not through caring for others. If you measure people primarily through care for others, you'll miss out on some pretty remarkable people.
