Because it works better if they're trying to have adventures rather than constantly plotting revenge at some group of heroes. They're not completely bad people, just a bunch of sociopaths trying to relax. They're mostly anti-government, which is why S.H.I.E.L.D. is their enemy. That, and SHIELD helped found interdimensional black ops, an arguably evil organazation that is attempting to arrest Dogbert.
