Nothing dishonest really. There was a need to make a paper for an institution that issues "degrees" and I did it. The customer evaluated that institution as worthy and honorable. I don't.
Cops overwhelmed by corruption become corrupt. Is that ok?
ofcourse is ok. We all get corrupt one way or another.
Politicians overwhelmed by corruption become corrupt. Is that ok?
yeap.
Gang bangers see corruption around them thus justifying their own corruption. Is that ok?
yeap.
Dishonest professors that make money to write fake thesis for dishonest students should be fired and put in prison.
what should happen and what does happen are two different things. The only reason you believe they should be put in prison is because you value academia as a "pure" institution. same about cops and politicians that you mentioned above.
Thing is, none of these institutions are pure. heck, their own essence is based on corruption. this is how and why they got to exist.
