heyy my bitches i'm back, here's my killer oc

her name is Мария Лебедева, i will just call her Mary, She was born into a cult, September 19th 1981 in Russia her mother was raped by the cult leader and got preganat with Mary, as and her mother ran away from the cult after she gave birth Mary, and the Ангел Божий (the group killer leader) helped the poor mother, healed Mary's mother back to health, but yet Mary's mother left her in her care and never came back for her so Ангел Божий placed Newborn Mary in a foster care home.

the foster care parents took care of Mary, but when Mary turned around 11-12, her foster father cheated on her foster mother, leaving her Depressed, and heart broken, when Mary tried to Comfort her, she ends just getting yelled at with hateful words, but one day her Mother snapped and pinned down Mary, as Mary begged her, and saying sorry over and over while crying Hysterically, her foster mother Split Mary's throat open with a cleaver, and burried Mary's body in the snowy woods of Russia, and left her to rot, but Ангел Божий found her diged up her body, Ангел Божий used her blood to Revive Mary, BUT Ангел Божий blood made Mary part demon and under the Control of Ангел Божий. 

After When Mary was 15ish, Ангел Божий made her kill her very own Foster mother with the same cleaver that her foster mother used to spilt Mary throat, and After that Ангел Божий made her kill even more every day if Mary didn't listen, Ангел Божий would have used her blood inside of Mary to if her her heart, or just cut inside of Mary to the point where Mary would have thrown up blood.
