What an absolutely tragic worldview you have... There's no doubt that there are disingenuous people (let alone complete grifters). But the fact that you can't conceive of anyone doing anything good just for the sake of it - let alone making genuine self-sacrifices, which happens ALL the time - is utterly shameful.

Moreover, if you are properly-aligned in life, whats good for others/the world is ALSO good for you. Even those who make genuine self-sacrifices would say so - at the very least, NOT having done it would be the real, unbearable, sacrifice.

I really hope you'll reflect deeply on this, and perhaps that it even haunts you - even if just out of pure self-centeredness, since the only people who you would ever have in your life with a mentality like this would necessarily be completely self-centered as well.

I am only making conclusions based on what I see, and I comment hoping people can tell me how I am wrong. I am still trying to figure this out, but all evidence points to what I said.

People never "do good" "just for the sake of it" - there is always a reason, whether or not the person realizes it. The reason could be, e.g., as I said, the desire to seem good, some kind of religious belief, etc. Ultimately, it is never "just for the sake of it"

I am also disappointed, and I don't know what to do with this, but I am not willing to become some kind of ignorant, delusional lunatic.
