Let the Trash Compacter cube its owner

[Lady Birb]

Personally I think reverting to Crush-Anyone state would make the cart virtually worthless. Not useless, but not worth the TC it costs, even if it were 1. 
The Janitor ( and by extension pretty much everyone) already has access to an item that can crush your enemy, but also crush you if they happen to grapple better. It's disposals. And it's much less conspicuous. 

It becomes a mobile trash chute guaranteed to end in your death half the time. 

No thx

People still buy the portapuke, and you can kill the owner with that. I don't think people will be less likely to buy the trash compactor if it could kill it's owner. In fact I am pretty sure that the wiki doesn't even say that the owner of the trash compactor is immune.
