Agreed, intention is where it’s at. Anything can be corrupted.

For the vast majority, I think everything is done out of, in part, selfish reasons. The actions done however vary widely in wholesomeness. To flourish in the act of giving one’s own life to serve other beings is, I think, of maximum wholesomeness.

It is also possible to have a sense of self but not be limited to it.

I think it just depends on where you’re at emotionally and spiritually. If you are fulfilled by serving others full time then that is indeed saintly and something to admire.
