...Okay so the real key to understanding Schuldig's opinion on Cobra is the fact that, throughout Schuldig's canon, he and his team basically act as the hired guns for no less than four or five people, in various capacities, so it's well within Schuldig's realm of tolerance to roll with Cobra in that respect. I mean, he's dealt with working for a guy who put mind-control countermelodies in his rock music so that people who listened to it would go off the deep end and go on rampages of violent terror from it — the stuff that Cobra comes up with is pretty much "must be Tuesday".

So basically, he's figured out that Cobra's a little megalomaniacal (a little?) and also that Cobra is at some reasonably high-up position in the Rocket organization, all of which spells out an optimal arrangement to Schuldig because that means Cobra's pretty easy to keep happy (and thus, to stay in his favor); moreover, because Cobra's a little less...cautious than some of the other Rockets, that also means that working for him probably means Schuldig will be subjected to less superior-enacted restraint than he might be otherwise.

Basically, what Schuldig frequently says is the honest truth — he likes to be a facilitator of other people's schemes. He's not really a big-picture, long-term-plan kind of guy; he does better with the nuts and bolts of "here's a mission, go do it". So that means he actually does really well with Cobra because then Cobra tells him to go put the fear of god in a supposedly psychic highschooler, Schuldig gets to fuck up a guy in a back alley, and everybody ends up happy with their role in the process save for the unlucky victim.

So yeah, he likes the guy a lot!
