He risked his life to save the world. He took Thano’s (Idk if I spelled his name right) glove with all six infinity stones and snapped his fingers to take all the power out of it and to also kill Thanos and his army, but it was too much power for Iron Man, so he died. All that power drained the life out of him. (Hopefully I explained this right. Don’t come at me Marvel fans).

Although, if you could communicate with them, you may be able to convince them to leave you be. Or not. Who knows? lol.
Not necessarily! There’s always a possibility that, if stranded at sea, a boat could come by and rescue you; if lost in the cave, you could always manage to find your way back to the entrance and hopefully escape.
