They only committed one sin - Greed.

It's a pretty normal human affliction, and in large I agree with you - while the effects were catastrophic - the actual act is not something that should be demonized, the people are not the problem, the system is - fixing the system is the solution, not blaming the people.

I'd go on even further and argue this kind of behavior is normal, and even healthy, and seen in any 'insider' group - I run SciFi conventions (so do nearly all my friends), and we were building a cards against humanity work-alike, many of the jokes were jibes against the attendees or the community within which we operate, no one thought anything of it, because its a cathartic way of dealing with the stresses of our hobby, in their case, its a cathartic way of dealing with the stresses of a very very stressful industry, and ribald and in poor taste it is - but as often is the case, poor taste can be quite funny.
