Is "intent" what makes all the difference? I think doing something bad unintentionally does not make it good, right?

Otherwise, all I need to do something bad is have no bad intentions. I'm sure you can find good intentions for almost any action, but generally, the end does not justify the means.

I'm not saying that those who act unintentionally should be given the same kind of punishment as those who do it with premeditation.. what I'm saying is that if something is bad we should try to prevent it in the same level, as opposed to simply allowing it or sometimes even encourage it. And this can be done in the same way regardless of what tools are used. I think we just need to define more clearly what separates "bad" from "good" specifically based on the action taken (as opposed to the tools the actor used).
