What moral standards determines if you are a good person?

I basically go with trying to not intentionally cause any physical or mental harm to anything that is living.

I fail at achieving that goal far to often.

• Not killing.
• Not griefing another. (in WoW terms that means to cause grief of any kind)

I think one can very well make up for himself whether his actions are for personal gain or to “do good”. In fact, “not doing bad” (i.e. not wilfully put others at disadvantage) can already be considered “being a good person” IMHO. A good indication of whether you’re doing something good is deciding whether you’re trying to have other people notice what you’re doing.
