So now, is that "kind"? Or is it simply "committed"? And are they two separate categories?
Separate but with an interesting relationship.
Your examples in this post are of commitment. It is born out of the desire to make things better and developed to their full potential.
Kindness is both a prerequisite to healthy commitment and a strong opponent to it. Kindness is all about avoiding hurt feelings, and it is unfortunately at times quite limiting once one has to deal with this imperfect world. Unleashed, criteria-less kindness can be very destructive.
