I remember back when the first game came out, people complained that Joel and Ellie just got away with the horrible shit they did (more specifically Joel since he did kinda massacre an entire base and destroyed possibly the only means for a cure). I feel as though this was some attempt to address that, that what Joel did had severe consequences on both him and Ellie, but it's so wrong headed, especially when the game makes you play as the person who murders the protagonist of the series.
You know what would have made this better? Maybe make Joel address the consequences of what he did and accept that his choice affected more people than just himself and Ellie. You can have Joel die, sure, maybe you could do something interesting with Ellie also having to address Joel's decision. This "cycle of revenge" crap is just disconnected from the previous game and its themes. There were a million better ways to go about this, but the game decides to go with the absolute worst idea possible.
