I thought ISIS were horrible in 2014, but looks like 2015 is going to be even worse...
This is very sad, especially for the children who are currently being born into the IS and will be indoctrinated from birth to do things like this. Most of these children will probably have to end up committing suicide at a young age (whilst killing loads of other people with a bomb of course...). ISIS need to be stopped (and no, killing all muslims is NOT the way to do it).
