Kids had it coming. He obviously had the upper hand in terms of weaponry and was going to make a deal with them when they first offered. Then, while he was looking through the loot they attacked him. Should have kept to the deal.

I don’t really understand why the guy keeps hacking away at doors in the end, looks incredibly tedious. But the kid is not particularly likeable either. My verdict is the true villain is this game.

Aw poor kid.
Small things of personal achievement can mean the world for some children.

Yeah, I agree with this. Guy was just playing the game, but I would've been nice to the kid. 

Edit: I also wouldn't be letting my kids play Rust. It's designed to be frustrating and tough and obviously kids have the emotional developments of toasters, there's no way a kid would handle the game well. 

I mostly do my best to help people that i notice are upset,i do not get why people get a kick out of upsetting children.

Yeah this is a parenting problem for sure,there should be time invested to slowly learn them about the risks and dangers of online communication and even then it should be monitored.
