You don't have a choice, that's the whole point. Sam sums it up perfectly when he asks Ellie "What if they're still trapped inside, without any control over their bodies" - that's what they're going through.
You should do some research on Cordyceps mate, you'll learn about how it affects ants and how it influences their behaviour.
Choice has very little do with it bud
No, I would eat Big Macs and become a Bloater in no time.
I have acquired the grade of Master in The Last of Us story/character/game knowledge as I have played it through 9 times.
... I have no life.
I would absolutely find a way to Tess myself. If there was an oppotunity to become killed as a sacrifice, great! If not, then I would simply end my own life. Just like Tess, I would not want to become one of those things.
If I got infected I would strap on a good helmet, ballistic vest/plate carrier if available. duct tape my joints w/ pads, duct tape some good gloves on and duct tape the upper/laces on my good boots to keep them in place. I would be a **bleep** durable runner/stalker/clicker.
