Good law disincentivises bad behaviour; But bad law never provides an incentive for it. That comes from individual circumstances.
Obviously and demonstrably false.
Example:
Lets say Society X has a law against driving into pedestrians.
Being an enlightened society, the punishment for breaking said law is not designed to punish the perpetrator per se, but rather to provide restorative justice to the victim and their family in as far as possible.
Thus, if someone drives into a pedestrian and the pedestrian is injured, the driver must pay all associated medical bills of that injury for the rest of that person's life.
If they drive into a pedestrian and the pedestrian is killed, then the driver must pay all funeral costs for the dead pedestrian, because no amount of money is going to bring the dead back to life.
Also, like most societies, the cost of lifetime medical bills significantly exceeds funeral costs in Society X.
Given the above law and punishments, the law as specified incentivizes people to make sure that they kill any pedestrians they hit (whether by accident or deliberately), which is obviously bad behavior which is being incentivized by this obviously bad law.
Now, not all people subject to this law will inevitably make sure to double-tap and kill any pedestrians they hit:
Some may value the lives of strangers more than any potential additional cost to themselves and will stop and try to get help for any pedestrians they (accidentally) hit.
Some may be willing to risk just doing a hit and run and hoping that they can't ever be identified.
Some may be perfectly respectable people who would be perfectly willing to take an injured pedestrian to the hospital, but frankly couldn't afford being saddled with an extra lifetime's medical bills without their family becoming destitute. They struggle with the notion for a few minutes before killing the pedestrian, drive home, get wasted drunk, and beginning a years long spiral of depression trying to cope with the idea that their failings turning them into a murderer.
Some may be rich callous bastards who now see the law as providing a license to kill people who annoy them so long as it is less annoying to pay their funeral costs.
etc.
Even though different people with different values and different tolerances for risk can plausibly react to this situation in different ways, the law has a net effect in incentivizing drivers to behave in a manner that results in at least as many and likely more dead pedestrians than if this law were not in effect.
Resulting in more dead pedestrians overall.
Which is bad.
