Yes, that was mostly the point - you should assume that nefarious actions are done for nefarious purposes. Assuming they are done for noble purposes risks normalizing them much more than the opposite. Your president has assassinated a foreign dignitary? Assume they are a criminal now. Perhaps in 50 years you will find out that it was of the outmost importance for world peace and prosperity, but it is far more likely that it was some petty revenge or power struggle.
