The DCI doesn't make SENSE

The DCI is one of the most widely accepted theories in the Five Nights at Freddy's community. This video takes a look at that theory and figures out weather or not the theory is actually plausible. Do we actually have enough evidence to say that the DCI was a separate group of five murdered children? I’ve never made a FNaF theory video like this before, so if I missed an important piece of evidence or you have a different interpretation, let me know in the comments!
