If you give a Sin a steakknife, He'll want a human to use it on.
When you go to the funeral home to find someone to maim,
He'll see the coffins that are made of wood.
When he sees the wood, he'll want some to hit people with. So you take him to the lumber warehouse to buy some.
When he sees the chainsaws that the use to cut the wood, he'll get excited.
He'll want a chainsaw of his own.
He'll want one so that he can cut down the tree in the front yard.
When he starts to cut down the tree, he'll notice the woodchips that fly everywhere.
Seeing the woodchips will remind him of the human entrails that fly out of his victims when he kills them.
He'll want a human to use the chainsaw on.
So you take him to the morgue.
Seeing the dead people will make him want a live human. So you take him to the mall to find a victim. When he has his victim, he'll want a dark alley to kill it in.
When you take him to the darkened alley, he'll slaughter his victim with the chainsaw. Seeing the entrails fly out of the corpse will make him want some fresh meat to practice chainsaw murdering on. So you get him a steak from the butcher's. And if he sees the steak...
Chances are...
He'll want a steakknife to go with it.
