Personally, I think Doffy would be a great start to the not killing villians exception. If Oda wants to start somewhere, Doffy is the best place to start. It is precisely because his character is so interesting, that his death will have a stronger impact. Also, because of evereything he's done, his unique background and his motivation force, killing him brings forth a sense of satisfaction as well.

In the perspective of Oda telling the story, I think it really depends on what Oda wants to do with him. If Oda wants to utilise him again, he'd probably escape. I doubt Oda will want to do another Impel Down breakout, so sending him to Impel Down would be counter-productive if he's to be featured again. To be honest though, I think if Oda wishes to actually finish One Piece before he dies, he's gotta start killing villians and stop leaving them with the open ended option of returning. At this rate, One Piece is gonna end with plenty of loose ends. I only fear that if Doffy joins the cast of out-there-wandering-might-come-back ex-antagonists along with CP9, Enel, Moriah and Crocodile, we might end up with a series where we have plenty of characters left unaccounted for by the end. Of course, I'm trusting that Oda has a plan for everyone. He's been pretty good at reintroducing old characters so far.

From the story point of view, I think it'd actually make sense for the Marines to do a public execution of Doffy. This would be the perfect chance to 'salvage' their face. Since everything has been broadcasted, it's bascially impossible to cover it all up unless they enact multiple buster calls to destroy all the surrounding islands that received the broadcast and immediately deployed snipers to assasinate every news coo flying around the world. The best way for them to salvage their reputation is to take to the front and do a public execution of Doffy, exposing his crimes fully and demonstrating their 'justice'. Good thing for them though, I believe Isshou had no knowledge of Doffy's status as an ex-celestial dragon. That bit would be something the WG definitely wants to cover up I'm sure.
