Mental illness or psycopaths

So I originally saw this image and was like wait what???? I knew they made him take that picture which is why he is so incredibly uncomfortable and crying but looked into the truth and

What do you think would cause this? If they just killed the children I would think they are absolute sociopaths but they killed themselves to and looked up how to kill themselves

What the absolute fuck was going on here

EDIT

Apparently these women were abusing and starving these children constantly and chose to end their own lives and take the children’s lives with them

The children apparently would seek help from neighbors

They drove from Washington to California to kill them and the one woman got drunk to have the courage

This is shit
