Lasair your far from a bad person. Very far
Just the fact of the field you work in, and the patients you have, is something to show how good of a person you are.
Things that make people bad are negative qualities like hatred and jealousy, envy and greediness, and also emotions like frustration/anger. All of this contributes to making a person do bad things. For a person to be bad most of the things that they do have to be bad things. We all do bad things sometimes, and sometimes we do bad things for good reasons. you are only a bad person if you intentionally do bad things to hurt someone knowing the effect, without caring.
