Why were Native Americans so eager to engage in the enslavement of other Indians before 1750?

Native Americans used slavery as a way of strategy in order to obtain freedom. They used to be whipped, tattooed, beaten, starved, etc. But once a person was enslaved, they had certain privileges and some kind of freedom. Men were protecting their owners, women would marry someone from the tribe and they would get a Hämäläinen title. Children would be adopted. Once they endured many ways of trauma and humiliation, they would achieve attain quasi - - status of freedom. Their children would be Comanches. The enslavement was over in 1850 and tribes decided to form a union and work together because Americans removed them from their own lands.
