My point is that it's not at all easy to determine who's 'good' and who's 'bad'. In fact I think those are extremely simplistic labels to tag people with, expecially when discussing what could amount to summary execution.
Is an enemy combatant with a weapon a bad guy? How about an unarmed enemy combatant? How about an enemy combatant with just a knife, or a rudimentary club? How about an armed civilian who might be an enemy combatant?
Is a bank robber a bad guy? If so, do they deserve to die? How about a white-collar fraudster? How about someone running from the police? How about a mentally ill person running from the police?
This stuff is never clear cut. It's why we have courts and military tribunals. If you can't think beyond 'good guys' and 'bad guys', I don't respect your opinion.
I'm still not sure what your point is. Are you saying that people in US government/military/etc who decide who to kill make bad decisions? If so, give some examples, and suggest how we can improve the situation.
I would have thought most people are somewhere in between.
