Well yeah obviously both are important. Ideally you have good intentions which leads one to act in a way that is perceived as good too.

However my point is that intentions is what tells more about what you're like as a person. An autist may be socially akward and they might act in a way an asshole would too but if you know they don't intend to treat you badly then you also wont judge them the same as someone who does it with the purpose to hurt you. You might still not want to be with them because it's emotionally taxing but you shouldn't think of them as an evil person.

If a someone bumps into you on the street by accident and you spill your coffee the end result is exactly the same as when someone does that intentionally but the intentions matter here a lot.
