Bad decisions are mistakes. A person doesn't randomly do something that is purposely a bad idea. Most of the time when something happens is when someone thinks it's a good idea. No one deliberately chooses to go against what they think is right, and make a bad idea. Most of the time when a bad decision is made is when someone is contemplating on whether it's a good or bad decision. When a really bad decision like murder happens. Is when someone feels trapped, and scared, they think they can't get away, and can't be free unless that person is out of their way. Consequences for murder are actually unfortunately not very lethal. It all really depends on what state of mind the person is in at the time. Consequences for a normal bad decision depends on the persons age really. If a person is a teen then punishment is being grounded, or told no. If the persons is of the age of 20 or so then a punishment is usually self pity.
