I personally believe that being "good" doesn't mean we always have to conform what other people think is right. And in the same way, being the right person doesn't mean that we have to be good or we must always do something good. I think it is important to point out that we, as humans, have our own meaning (or ways) as to how to be good or how to have a good heart. Just because you have said something terrible to a person doesn't mean you don't possess a good heart. It all comes down to your intention, your perspectives, if it is pure and genuine.
