Rather than any attempt at temptation and corruption, Mark Rein Hagen opted to punish characters with schizophrenia for stealing candy bars. Because that's what I think of when I hear gothic horror.
The Wankpanzer is worse than anything that came out of Detroit in the malaise era in the late 1970s. If you built a car with the frame of the Chevy Vega, the gas tank design of the Ford Pinto, and powered it with an Oldsmobile diesel engine using the Cadillac cylinder deactivation technology from the V8-6-4 engine mated to a THM200 transmission, and you had it assembled on a Friday afternoon before a three-day weekend, it still wouldn't suck as much as the Wankpanzer does.
