Is it a person's thoughts or actions that make someone a good person?

I'm going to start off by saying I know I'm not a good person, I lie, manipulate, steal. I'm selfish and self centered, I have anger issues, I'm greedy, sinful, and I don't care about fair nearly as much as I do making it seem fair that I got . The thing is though, that I don't get caught; I make sure my lies are as close to the truth as possible, my manipulations are usually subtle, I rarely steal anything major, usually something that could easily go missing or something that can be easily hidden with no witnesses. I hide my anger and hate behind a mask of smiles, and I've trained myself to be helpful automatically. I constantly evaluate myself, my interactions with others, and my motivations, and while everybody around me believes that I'm an annoying, slightly lazy, trustworthy, mostly great guy with maybe a few issues, but otherwise normal (yes, I have asked). I'm able to fake empathy enough to help people through their problems, I'm a trustworthy confidante, and I work with Alzheimer's residents where my job is to keep them happy, engaged, and content, which I am very good at. So is a person a good person if everyone believes they are, or is the only way to be a good person to do the right things for the right reasons? I do little nice things for people all the time because people notice the little things like offering help, and responding with no hesitation the way people expect a good person to do. Considering all of that, could I still be considered a good person?
