I normally have some measure of sympathy for people who blindly run code that is unexplained or under-explained (e.g. the many "curl | bash" installers). But blindly running code that is specifically called out as having weird and unexpected behavior is like driving your car right through the bright yellow "bridge out" sign that's blocking the bridge.

It doesn't mean he should be cruel, it just means he is statistically more likely to be cruel.
