Better put my idea up here before I forget it and to share what is going to happen:
Basically the dwarf will stand a little bit away from it, and the things that it creates should be in the middle. So you take the gobby, put him in the middle by making it a pit or something, optionally knocking them out with the tazers I will make. Then once the victim is in place, you will have three options:
Execute. Releases a cloud of gas (Because that is the only way I know how to activate syndromes. Just pretend it is a needle to avoid unfortunate implications....) that kills everything with lungs except dwarves. This one is made to execute every prisoner, while the other two only work on goblins, this one works on things like elves, too. I suggest setting it on repeat, it will cost nothing and you do want to be sure to actually kill it.
Interrogate. Only works on goblins, and will take one full bucket of water to do (In order to take more time, since being instantaneous would ruin the effects). It would release a gas that can do several things: It will either A: Turn the goblin into an "Interrogated prisoner" which drops blueprints on its death which will take several seconds. Blueprints can later be used to make a missile silo, if I get around to it. B:Turn the goblin into an "Angry Goblin", which gives the goblin a "shank" and makes it go around attacking things until you shoot it down.
Re-education. Takes some alcohol and a hostile goblin. While it takes a valuable resource, it can turn a goblin into a "Reeducated Goblin", that acts as a pet, effectively joining your side. But it has a much higher chance of becoming the hostile goblin, to add some risk.
I may also add some of his other suggestions, like "Zombify", turns the goblin into a "Goblin Zombie" to keep up with the modern fantasy thing. I would make it take a blueprint, but have a 100% chance to succeed and make it infect other goblins that it bites.
At first I was like "I kind of feel bad for doing this" but then I was like "But this is dwarf fortress. We all have five things worse then this guarding the gate. At least now the goblins have a chance"
