I believe strongly that it is one’s intentions that dictate whether or not they are “good”/“bad”. It is not actions we should base our judgement, nor achievement, but intention. A person could be completely kind and selfless with impure intention, changing the nature of their actions completely. So while I don’t think it’s possible to have good intentions all the time (to be wholly altruistic), I firmly believe that it is a way in which we can judge a persons goodness. It is also a way in which i find forgiveness easy, knowing one had good intentions with bad execution is often means to just live and let die.
“Kindness is an inner desire that makes us want to do good things even if we do not get anything in return. It is the joy of our life to do them. When we do good things from this inner desire, there is kindness in everything we think, say, want and do.”
-Emanuel Swedenborg
(also curiousity, a friendship dies when you stop wanting to know more about the other person, a good person offers their curiosity unwaveringly)
