As for me, Killing Trevor felt like the right thing to do.

The Third Way.
By keeping all three characters alive, it gives you more gaming options moving forward.

"I have only done two endings (killing Trevor and deathwish). I prefer deathwish as you get to keep all three characters, but if you kill one the other two get more $$$."
I keep all three alive and each have just over two billion in the bank and they each have another six hundred million riding the stock market. It's the only way I've found of circumventing the money limit.

I've done all three.
I did not want to kill them.
Trevor's was hard to watch and Michael's turns Franklin into a new Michael.
I don't see why you would kill them when there is a third option, that one is definitely the best. Big shootouts and assassinations plus you can still play with all three.
Well I kinda hated Trevor. He's insufferable! Also, I thought Micheal would be able to afford the Golf club with Trevor's share, but now I know that its meant to be a long-term thing. Even if Micheal wanted to hit the $150 million mark... Since the only easier way is doing the taxi mission non stop or waiting for a weekly income from his other properties (Bar, Theater, etc.)

It was not my decision to make
It was Franklin's
So, I killed Trevor because whatever Franklin has is because of Micheal giving him the opportunity and Franklin owes him a lifetime, and would be a traitor if turned his back on Micheal.
If it was my decision I would have killed Micheal since he was a shady liar who can't ever be trusted I think.
