Humanity is fundamentally and inherently evil, and being happy about humanity depends on delusion and ignorance. The only way to sustain lasting happiness is to turn a blind eye towards human atrocity. If you know the truth, you cannot unknow the truth. You are destined to being exposed to reality, which can disappoint you and lead to permanent depression. The solution is to shield yourself from humanity and live off dividends. Gradually transition away from forced interactions with people e.g. through work and family and move towards a more flexible lifestyle that allows you to move in and out of relationships and friendships with ease. There is nothing wrong with moving closer to feel warmth, but you must have the freedom to step back lest you burn yourself trying to achieve warmth.
