Where do we draw the line?

As kids growing up we had loads of aunties and uncles both by blood or acquaintance living with us and it made growing up colourful , for the past 2 days a video has gone viral of an 11 year old girl molesting or can I use d word hon sex with a 4 year old boy under the instruction of a sicko(permit me to use this word). A lot of people have viewed this video. Apparently it happened in delta state. This is pornography of d highest order & so I ask WHERE DO WE DRAW THE LINE?
