could Hannibal have regretted his plans about Will at the season 2?

I'm rewatch season 2 and his trying to convince Will that Matthew's murder was from that copycat and clear all of Will's doubts about himself. then he killing the judge -i know he was angry with the judge for his decision- but that might be his attempt to start the case from the beginning about wanting to start the relationship between them from the beginning? i'm probably delusionel LMAO what do you think? -sorry about my english-
