Tim.
Loves his everything except his origin. Spiderman-esque hero is fine, but having him as sidekick for Batman when he has home and without his parents's consent just damage Batman's character as an adult who let a kid jump into danger. Making Tim's life more egdy and depressed after he got Robin title helped that point.
I will reboot him as orphan maybe but just like Bruce he's loaded with money but no relatives. And keep everything else, like he deduced Batman's identity, willingly want to be Robin to save Batman and everything.
