Nailed it and I'm extremely disappointed
It was some what anti-climatic but it worked for me. I didn't mind that though. They've teased this being the way he'd go out pretty much since the very beginning of the show. One of the earliest scenes shows him touching his dads Motorcycle so they've been setting this up pretty much from the beginning.
I was glad they didn't go out having his guys kill him with the whole Mayhem vote which IMO would have absolutely sucked. I got what they wanted from the show here at the end. He was making sure to do exactly what his dad did. To tie up all the loose ends, to protect his club, and to get his children out of the life forever. The only thing is he didn't leave anything or anyone behind like John had with Gemma that screwed up his plans. For Jax he got exactly what he needed out of how he ended it all. He got his club away from their problems and out of any trouble for the things Jax was going to completely end and clean up before dying.
Plus he made sure to get his kids out of the life, away from the life, and to could go in peace knowing that he set it up to keep them as far away from being like him or in his type of life as humanly possible.
That was the most emotional, and tough, scene in the final episode is that whole sequence when he's explaining to Nero what he wants and then telling his boys goodbye for the very last time. Admitting to Nero that he knows he's not a good man, can't be a good man, and didn't want his sons to love him or be anything like him. Wanting his sons to grow up hating everything about him so that they'd never be like him was so emotional and I felt just perfectly done.
And of course, as usual, I couldn't help but feel so horrible for Nero.
So, yeah, anyway I felt like the ending was exactly what it needed to be.
