Perhaps driven by character and feeling, I have always considered effect to be at least as important as intent--and almost always more so. When it matters, intent tends to augment, mitigate, or determine the degree of fault or laudability, rather than rendering an act moral or immoral. If no one is actually harmed (or is at some point likely to be) by an act, we don't generally worry too much about it. If you accidentally push somebody in a crowd, or push them to get past while being chased by murderous mobsters, that's not so bad as pushing the same person simply because you can, and it may be excused, but you probably still owe them an apology. If they stumble and fall after you shove them, you are responsible for whatever injury may occur. If you push them into traffic, and they are run over, your possible sentence and likely charge may be less than if your actions had been malicious, but there's a good chance you'll need legal representation. Broadly, if no one...
Anything, everything, and nothing at all for years at a time.
