Nobody with a brain does really give a shit about morality, it's just stuff for the masses, when stuff like this happen, it's a run about who gets more credit out of it, like look at us, we are doing a great job, and so our taxes are fine, and no way that we are corrupted piece of shits that sometimes we do stuff only to set up examples and justificate our existence/spending
