I think you guys are being really mean spirited about the idea that what amounts to a teenager who's only played video games (and has literally just witnessed for the first time, someone's actual death... several times) should've been level headed and able to actually think through the situation. Yes MC is dumb for not taking everything as serious as he can. But people do that all the time in real life, literally getting themselves killed. Snap decisions are hard enough without the pressure of looming death. You can bring up the goblins for reference, but at that point he was kinda stuck in "Is this a game?" mode.
As for the other guy who grabbed MC, he's prob just going to slap a ho for saying "I could've done more". Survival shit or whatever.
