Torture and Sacrifice

If a person does something for someone else, there is a simple way to know if it is torture or sacrifice.

Respect.

If what you do is respected, then it does not matter whether it is done willingly or unwillingly, or how difficult it is.

If what you do is not respected, then it is torture. It doesn't matter if you do it willingly or unwillingly. To have what one gives of oneself lack respect is to feel foolish.
Take away respect, and the noblest words or actions are simply torture.
