I used to have RP like that before as well, but to be honest it always ended dramatic and the RPers were never happy in the end so that the RP got rejected again. It's up to you if you want to risk your chars death. But beware, that if you grant everyone on the server to kill your character after capturing him, it will be the same as I said already. Drama RP including character deaths is an case for its own.
If I would be you I would try to avoid such RP. And in the end you're not happy about the results of the RP you have done, except if you really badly want to get rid of the character. Think about it again before doing so and think of people, who simply could use this option "for the lulz" to kill off your character without much roleplay.
Just my thoughts. I wouldn't do it. But it's only me.
