Do you actually think some people are worth killing or should die?

The #1 question could not be asked because the code missed it as a duplicate, so, you get this one; life with it

With the 9/11 remembrances not truly in the past and people saying how heinous the attackers were, for wanting to kill that many people, or anyone for that matter, and wanting to be seen as better than the attackers, who appear not to respect for human life. Based of this question, it seems that people will make exception, there are some they will see as less deserving of life. Stripped to its core, to use the past of a person as the criteria on if they deserve to live in the present, is still making a judgment on their fitness to live. Is that judgment vastly different from those out there that would kill themselves and other because they placed a value on those people’s worthiness to live based off past or present facts?
