Both choices do kinda have the same outcome, because in both endings Silas aknowledges how revenge destroys him and he's left hollow. Difference is that Bob/Roscoe lives in one and dies in the other
The redemption ending is the exact same thing as TLOU 2 shitty ending. Where you rip hell apart to reach your target and give it up in the last second.
I thought Silas was telling these stories for attention, but a part of me also thought that what he was telling was true, I almost agreed with Jack, that I was so surprised by the end of the story that I chose to take revenge.
