The detectives couldn’t catch up to him without cheating like crazy. How is this justice? Breaking every law possible just to get close to him. They were beneath him. Even when they had him they couldn’t control themselves to let justice be served.
Legality and morality are different things. Now, I don't think cops should break the law, but there's a difference between the law, morality, and justice. These are not necessarily the same, although there is a lot of overlap.
John Doe murdered people - a lot of people - and he did it in horrifying ways. This is a sick man, a psychopath, and clearly has no moral high ground. Were the detectives right for bending the rules or breaking them? Nope. But that doesn't mean they sank to the depths of John Doe.
While the cops did cut corners and did things that they shouldn’t, it all pales in comparison to John Doe forcing a man to rape a woman with a blade dildo.
I was raised on a diet of fairy tales and action movies where good defeats evil and evil dies, so I got my morality from those areas albeit reality just doesn't often work this way much at all.

Worked for Dirty Harry in catching the Scorpio Killer
It's really stretching to determine that John Doe has moral high ground over the cops who bend the rules a little to catch him. John Doe is a monstrous, time bomb monster, whose aim is to murder more victims, so he must be stopped at all costs. He deserves to die, one way or another.
