The tragedy of evil is that in trying to stop it, you create it. So if you want to stop doing evil actions, you also have to stop seeing evil because to see evil you must project evil... therefore, you create evil. If you genuinely want to be moral, you got to make a counterintuitive move of giving up all morality. All of your moral rules give them all away. Only then you will truly be moral but if you go around touting your morality, and telling people how moral you are and how immoral they are, that immediately tells that you're not embodying your morality. A genuinely moral person would never do that because true morality is not based on rules, it's not a self-image that you adopt, it's not a list of 10 commandments that you follow. When you think you're so righteous and so moral, you will go and kill people in the name of your morality which is precisely what creates evil.
