There's this one Buddhist thing:

“Watch your thoughts, for they become words.
Watch your words, for they become actions.
Watch your actions, for they become habits.
Watch your habits, for they become character.
Watch your character, for it becomes your destiny.”

Which kind of ties back to one of its main things on 'not judging because you never know a person's intentions' and stuff.
And I do believe intentions are very important, it essentially separates a person from good or bad.

And we always call the people who perform good deeds with bad intention to be bad, but what about those who perform bad deeds with good intention <- if that;s possible.

What are they?
Because don't their actions leave a larger mark than the thoughts in their heads?
I'm confused.
