Utilitarianism

In my philosophy lecture we’ve been discussing the views of utilitarianism. A utilitarian essentially believes that every action you perform should completely maximize the happiness of the individual whom the action most affects. Of course there are a lot of controversies, issues, and other factors that play into this ideal, but recently we’ve been focusing on the utilitarian’s perspective of judgment of character. What makes a person good or bad? Some believe that the actions directly reflect the person’s character and depth of intentions. The utilitarian, however, stands firm with the whole "not of the act, but of the agent" ordeal. Actions could be morally wrong, but intentions tower over these actions like a looming unbreakable force. I’ve begun to wonder how a utilitarian (or any person in general) would perceive me if they knew the length and carelessness of my actions. Within these past few months I've undoubtedly failed to be the best version of myself I could be. Daughter, friend, girlfriend, human being. I've made decisions that benefit one while simultaneously bringing others down, but all the while meaning well. Is the phrase "actions speak louder than words" complete bullshit? Is there any chance that I still make the cut for the "good person" category despite my despicable actions?
