Good intentions aren't enough. People have good intentions when they set a goal to do something, but then they miss a deadline or other milestone.

Good intentions are not enough. They've never put an onion in the soup yet.

And good intentions? These scared him the most: people with good intentions tended not to question themselves. And people who didn't question themselves, in the scientific world and beyond, were the ones to watch out for.

It's exhausting, tiptoeing around someone who barges into your life with good intentions.

...it's true that some if the most terrible things in the works are done by people who think, genuinely think, that they're doing it for the best, especially if there is some god involved.

Hell is paved with good intentions.
