There are many types of bandits as there are many types of stupid people. The more intelligent kind of bandit is the one who’s behavior yields to them more profits when compared to the losses caused to other people. But these types of bandits are not numerous.
Most bandits yield gains that are inferior to the losses inflicted on others. An example is someone who kills you to rob you of fifty pounds.
But while there are different kind of bandits, there are fewer kinds of stupid people. Most stupid people are basically and unwaveringly stupid.
In other words, they perseveringly insist in causing harm and losses to other people without deriving any gain, whether positive or negative. There are however people who by their improbable actions not only cause damage to other people but in addition hurt themselves.

This is a sort of super-stupid people.
