Epiphany during Rewatch (possible spoilers)

I was a big Grey's fan back in the day. I religiously watched the show up until Mcdreamys death. At the point I got frustrated with the amount of main character deaths and have up on the show cold turkey. I have not seen a single episode since then. A few weeks ago I decided to pick it back up so I started all over again.

After rewatching everything again I find Derek condescending and kind of an asshole. Honestly he is one of the least likable characterd of the show. I have no idea why his death was my tipping point. George or other characters were far more enjoyable.

I am on season 11...only 10 more to go while I try to get back to current.
