The choices are, Damian, Dick, Tim or Jason.

I feel like Jason's the most likely to put himself in a situation where Batman would need to kill him.

Dick Grayson, why you might ask? Because all his other Robins have already died, so if he kills Dick Grayson, he'll come back and the Bat-Team would basically be a team of Zombies....take that in for a second.

We all know Tim isn't staying dead

Jason - and it will be false death...

Well his least favorite is certainly Tim, not by much mind you. Though to kill one of his boys.. that would have to be one extreme situation.

Either one of these

- contingency plan

- kill himself

Probably Jason, but I can't imagine him ever being in the situation where he kills a Robin.

So the situation would be, a psychopathic killer kidnaps all of his robins, to get to batman. So he asks him to choose, and if he doesn't choose in 10 seconds he would kill them all.

On second thought... he will kill anyone of them !!! And its not matter who will that gonna to be bcs, it will be false death !!!

@drarcania: Unless you mean ressurection, it couldn't necessarily be fake because the killer would shoot the one batman chooses. The attack would be sudden so their would be no time to prepare. I REALLY should have mentioned all of this earlier and worded it better.

I'll try and assume this is a serious scenario where Batman assumes that they really will all die and ignore the fact no one ever stays dead.

Firstly he wont kill Damian because he's his son and died relatively recently.

I actually don't think he would kill Jason because of the guilt he used to feel the first time he died and I imagine he might still carry some guilt for failing him.

That leaves Tim and Dick. I think Dick being the eldest would probably try and step up and tell him to kill him because of the whole older brother thing. Let's be honest though, Dick is probably the best thing to ever come out of the Bat family and I could see Bruce being sentimental and saying the world needs him more than any of the others.

Honestly I can't imagine Bruce ever being able to do it but if he did make the choice I would guess it's probably Tim or maybe Dick.

@spyrobrine: Whatever... i'm not just smart as Batman ( :P ). Whatever you say - he will again find a way to you believe, that he kill one of them ;)

@drarcania: Huh? What is that supposed to mean?

He's not dead tho.

Bruce would rather see the universe destroyed than be forced to kill one of his four sons.

@drarcania: is that supposed to mean that he would find a way to fake it?

@spyrobrine:

probably

Tim Drake is dead, he died in Detective Comics a couple of months ago didn't he?

At the end of the comic it was revealed that he was captured last minute.

Mr Oz teleported him to his fortress right before Tim was hit because he was figuring out "too much" (aka he knows about the flashpoint) so he's alive and imprisoned.

Depends, i think bruce would off himself before doing that to any of the robins, or that he would succeed or fail looking for another way, but he would never pick.

If the question is whom he likes the least? probably Damian. If we go for who is the least useful to the cause? probably Jason.
