Dick didn't believe he was rude. He offered many people second chances, most of whom didn't deserve it. He even gave Bruce a second chance, despite thinking he didn't deserve it after being a terrible father. Dick considered himself a nice person. After all, he was a vigilante, putting others' needs before his own, treating everyone with respect, and focusing on making others happy.

When Dick established the Titans, he was confident nothing could go wrong. That is until you joined the team. You were Deathstroke's - Slade Wilson's - child. The idea of working alongside you was chilling. Your father had attempted to kill him and his friends multiple times. However, Dick didn't see himself as rude, so he tried to be friendly. Unfortunately, his trust issues got the best of him.
