The pokemon are happy with a good trainer and not with a bad.
The pokemon are not the slaves of human. You have to remember about charizard and ash. When charizard refuse to fight. Ash couldn't do anything. So, charizard is not a slave. If he really want, he could go away but he stay with ash.
The trainer uses their pokemon to fight, but when a pokemon is hurt, they walk... no they run to a pokecenter.
Pokemon and trainers share a particular bond. Nothing can break it.
So, no I disagree with the ambitious project of the team plasma.
