That's just natural selection doing its job. Weeding out the crap that doesn't deserve to exist.
It reflects badly on environmentalists, as crazies with weird ideas, that leave the rest of us scratching our heads wondering how they could be that crazy. Maybe they're not all that crazy, but there certainly are many among them who are. Eco-terrorism is prevalent in pursuit of their cause. Although this is the first eco-suicide I've ever heard of.
That's way out there over the deep end.
