Or 'caritas' - which doesn't really mean 'charity', but 'showing one's love for GOD and dedication to Him by seeking to do good for other people'. Which many faiths practice: Buddhism is noted for extending that 'caritas' to animals as well.
I DO agree that 'kindness' with an ulterior motive of trying to advance oneself in some way is utterly reprehensible.
One of the best expositions of this concept comes from the Sufi saint, Rabia al-Basri
Rabia al-Basri | Sufi Poetry
If I Adore You
If I adore You out of fear of Hell,
Burn me in Hell!
If I adore you out of desire for Paradise,
Lock me out of Paradise.
But if I adore you for Yourself alone,
Do not deny to me Your eternal beauty.
This concept is not limited to religion alone, for in at least two organizations in which I participate - if it is suspected that someone is 'hoping' to be accorded an honor, they obviously have the wrong mind-set to ever be cited as an example of the organization's asprations.
