Feeling doubt or hesitation about doing something because you think it might be wrong.
Scrupling can show that someone is careful and thoughtful about what they do.
Examples:
She is scrupling about whether to take the money.
He is scrupling before making a decision.
They are scrupling about what to do next.
I am scrupling about eating the last cookie.
The man is scrupling so much, he can't decide anything.
Stop scrupling and just do it!
