It is one thing to dislike someone, but regardless, no matter how unlikable we may find them, how destructive they may seem, to wish death upon someone is hardly the remedy, and lowers us to the level we claim that they may be. That would be missing our own point.
Also, an innocent bystander is dead, and another is in critical condition. They're not just collateral damage in some political game, they're people, with loved ones, and they did nothing to deserve this.
This is a sad day.
