Most of you are missing the point...
It's not the fact Johnny died that pisses people off, that may be the instinctive reaction but it's not the cause. It's how and why. As said in the game itself, it's not the destination but it's the journey that counts.
It's the fact he died while hugging an obvious lunatic. The guy wouldn't hug Elizabeta Torres for the exact same reason that ended up killing him.
I think Johnny would bring Ashley to LS actually. As I've said before in that massive post, Johnny's main character feature and weakness is the fact he cares too much and puts the weight of the world on his shoulders. He might have said at the end of TLAD that it was over between him and Ashley but that's a 'rational' reaction he's giving because he knows that she is no good for him.
However considering everything he's been through his will weakens and he gives into his 'protective' instinct where he still cares for Ashley. It's the same reason he could easily turn to meth. His character and will may be far stronger than most people, even for GTA protagonist standards, but he faced far more adversity than any of them.
Trevor killed him in an incredibly cowardly way, appealing to Johnny's weakness, then killing him. There are two issues with this that people are having trouble digesting hence the outrage.
- Johnny would be unlikely to ever weaken to that level. He may be a broken man sure, but he wouldn't hug Elizabeta who while a psychopath, she's nothing compared to Trevor and to a point Johnny trusted her. There was a better way to show the damage done to Johnny.
- Johnny doesn't die while protecting his brothers. A much better way to both show how Johnny is a broken man and how dangerous Trevor is would be to have Johnny trying to save his brothers/Ashley and dying in the attempt, almost resigned to his death. Somewhat similar to how Niko supposedly kills Jim. We don't hate Niko for that, even after we know Jim.
The way it's done however results in people hating Trevor and hating being forced to play as him. I don't want to even bother with any of Trevor's extra side quest stranger stuff and what not because of this and I hated playing as him.
The point is the same destination could have been attained but the journey could have been different and the effect and taste in people's mouths could be better. Would we be still moved by Johnny's death in the same way? Yes but we wouldn't hate Trevor anywhere near as much in consequence.
Everyone is 'really pissed off' with the death of Johnny...
Maybe this was Rockstar's plan? If it was, it's clearly working.
The question is why though? Sure being sad/pissed off at Johnny's death might be a nice idea but the result in the way its done is that we also hate Trevor.
Why have the second part of that for a protagonist we have to play with? I cannot come up with a satisfying answer.
