behave considerately

[optimistic pessimist]

Hi teachers!

Does it make sense to say , "You should behave more considerately." to someone who is really self-centured and doesn't care at all about the people around him?

Thank you!

'considerately' as the adverb is very rare e.g.
They considerately withdrew." - they showed consideration (say, for someone's need for privacy) and left the room.

For your sentence, we are more likely to say:
"You should behave with more consideration (for others)."

Or tell them to show some/more consideration for others.
