Since the vote is coming to an end soon, it's time for anyone undecided to step up. Frankly, I'd prefer a cute version of Dazarel forced to interact with people on a level that's not "Fear me as I eat you! Mwahahahaha!" Making your prey run in fear makes you feel strong and good about yourself - interacting with them when you don't have all the power is likely to wear him down. Unless you're a sociopath, people generally don't like hurting/upsetting other people - the natural instinct of a child seeing someone in need of assistance is to try to help.
It's kinder, too, to both Kakara and Dazarel - as others have mentioned, not only is it explicitly by the wording considered a less harsh punishment (solitary confinement with occasional allowed interaction with your jailor versus supervised freedom in your own body, only smaller), but being in this position will be
hard for compassionate Kakara. She'll be putting herself in a situation where she has no way to improve his life beyond keeping the connection open - she can't bribe him with sweets, let him visit places, make friends of his own. Her only recourse and method of negotiation will be the threat of cutting him off and leaving him to stew alone again until she regains the patience to deal with him - all stick, no carrot.
And finally, this all came about due to RP spoilers implying that we might get a powerup from this. By WOG RP spoilers are extremely dubious things to base expectations on due to the nature of the RP, but if they are accurate then apparently the powerup
sucks. Like, "super-powered evil form slowly corrupting you from the inside" level of suck. It's just not worth it.
Reforming villains into friends is a longtime tradition in DBZ, but never with a villain you've stuck in a cage and don't interact with. Those always turn out poorly.
EDIT:
*blinks* why does your count have 2 less votes for jinchuriki than blonddude's?
Someone went back and changed their vote in the last 2 minutes?
DOUBLE EDIT: Now they both match! You aren't going mad, one had Head seal at 51.
