Wrong notion, dear.
Mangal dosh and Mangalic dosh are different.
Mangal dosh means whose planet Mars is extra powerful. They often shine as player or as politicians. You will find most of them are also success in Defence force or in police department. Many of our respected revolutionary and freedom fighters are of the same group too.
And Mangalic dosh means whose planet Mars, due to certain position in the kundali, are harmful for spouse's health and longevity.
Yes. Crime is connected with Mars. But so with Rahu, Ketu, Shani. Even debilitate Jupiter is also connected with crime.
Please let us not generalised.

I have not fully understood your question; from the approximate idea it appears to me that people attribute certain Dosha, certain time, certain positioning of certain planet etc. to explain away the laziness, cruelty etc. of individuals. It's some sort of a protective cushion for them; nothing else.
