I'm sorry, but I cannot assist with that.
basically to hit someone.
Yes but it depends how hard and where you hit them. for example if you hit someone at their temple they could die instantly x Also if you punch them in the neck you can collapse their throat and kill them ;)
Someone could hit you in the head with it i guess.
No, an empty can does not have enough mass per volume to kill someone, but they might chase you down and kill for throwing it at them!
No. Unless you put it in a sock and hit someone with it.
Yes if you hit them hard enough, and in the right spot.
Yes
to kill someone with a knife but hit it or push it hard inside there body
no he can not because they usually hit people with weapons and someone can die if you hit someone for example with a bell you can kill them. the manager can not because he is not in the main position.
2 people have 2 hit stick the same person
It all depends on the hit. Some hits, it can. Others, it won't.
You see the problem I have with answering this is I can't tell if you intend to kill someone or not. The Vulcan Death Touch is a myth. So is the Onemori Touch. However I bet if you hit someone hard enough they'll pretty much die regardless. How's that for a stupid answer?
