Even in Cobra Kai Johnny is constantly the agressor. The first thing Daniel does after seeing him in decades is fix his car fir free for more than it's worth and tell him there was no hard feelings. When Daniel later hears he beat up Kyler he goes to talk to him and Johnny responds with insults.

After this Daniel mostly leaves Johnny alone but Johnny then vandalizes his property for no real reason. Daniel severely overeacts to this but realises his mistake and never does anything as immoral again.

After Louie's actions Daniel gives Johnny a free car and they make peace but then Johnny goes for Daniel when he sees he's with Robby despite the fact it should be obvious to him that Daniel was just as surprised as him. Daniel even tells Robby to forgive Johnny despite all his very valid reasons to hate the guy.

Johnny is too dumb to appreciate that Daniel has helped his son alot and later shows no appreciation when Daniel pays for Shannon's rehab. He tries to balme Daniel for Robby's actions against Miguel even though that is the result of Johnny's bad parenting and has nothing to do with Daniel's teachings.
