How can someone do this to their child????

Last week a friend of a friend's daughter who was 2 was raped and injured to the point where she needed a hysterectomy. The situation is very sad, but tonight I found out that not only the mother's boyfriend did this, but apparently the mother did this with an object.

What kind of sick twisted person could rape their own child??? What the hell is wrong with people?? Especially a MOTHER!! OMG I Could kill someone tonight. I hope this mother is burned in hell!! That is just so wrong!! That was your baby! How could someone do this shit??? OMG I'm crying again!
