Many would like to claim or would like to say that a life led by logic and reason devoid of emotion would be a better one. Logic and reason are cold, and without emotion, callous.
For example, the Iranian leaders proclaimed that they will destroy us. If only logic and reason were used and it was determined that the threat was real, the final decision would have to be total genocide for the Iranian people. All of them, down to the tiniest infant. It would be the only way to insure that the threat never occurred from that quarter again.
This reasoning would apply to any petty dictatorship or other type of government that threatened to harm us. The only solution would have to be the final solution so as to guarantee no threat from that source ever again.
