No, wait, I CAN blame them for trying.
Headline pretty much says it all: Students Strangled Brothers in Hopes of Holiday
Can’t say much for that boarding school - at least with a school shooting it usually seems to be someone who gradually builds up to such a point that they explode in a violent outburst. This case sounds just so cold and calculating.
I choose to believe that the three simply didn’t understand death - didn’t realize that they were taking away another person’s life, and that that was the end of them; thought it was simply like stepping on a few ants or something - they only considered their goal; and that this was the only way to achieve it.
The alternative (that they completely understood and respected what they were going to do) is just plain scary.
