I was Edgar in the robbery, my PoV is..
I was running with my friend trying to get more food to survive when we saw him running across the field,once my friend initiated we told him to get on the ground and drop all his gear.we took most of his stuff but left him with some food water and an axe. once he called "//crap RP" i ran back and threw my blaze at him( with two bullets).
With there being no zombies to fend off an axe would've provided the protection he needed and we gave him food and water so he could've lasted until he found a town(which he was near),and he had a backpack to hold the food and water until his friend showed up.
And for the need to rob someone it was for the gear,for us to tell him what it was about would've been self explanatory so we felt it wasn't needed to say,and for us to wait for his friend would've been suicide so we bolted.
