The only thing we're guilty of here is hasty good intentions,

Hasty is still in contention. He has done some good things.

Intentions are nice, but ultimately intentions don't really matter because they only exist inside you.

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.
