I understand that it may seem wrong to celebrate the death of a human life and even, to some extent, why this is the case, but I have a very hard time with the notion.
When discussing death in another context, most of us would probably agree that there are fates worse than death, that death cannot be avoided, and, in the absence of a belief in some form of Hell, does not justify our fear of it. Death is not our enemy and we all need not be united in defying his aim.
Whether Gadhafi is a truly evil character or the twisted product of ruinous social influences, his continued life would have meant continued suffering for many people. The fact that through most of his life he was the primary source of the suffering of many more people need not even be taken into consideration.
It's not as if the poor bastard was simply a carrier of deadly disease. If he was and the death and suffering he caused hundreds of thousands of people was essentially through innocence, we might feel funny about taking glee in his death, but there would be reason to celebrate the end of such a horrific danger.
In this case there is no innocence of intent, and someone can probably make the case that Gadhafi, at times, took glee from the death and suffering he caused.
That he is dead is a good thing and if there was a Death to praise, I would praise him for finally getting it right.
The people in Libya who suffered under his rule, certainly have reason to celebrate his death, and my bet is that there are no few number of them who feel he didn't suffer enough on his way out.
Certainly not criticizing anyone for not wanting to celebrate his death or in thinking there is something wrong in such celebration. I'm just saying I don't see the sense in feeling that way.
Even the banal explanation is far fetched. Celebrating the death of someone like Gadhafi does not coursen our respect for life and even if it did, the measure would be so small that it could hardly be connected to future acts such as those of which he was guilty.
There is nothing noble in celebrating the death of a very bad person, but I don't think there is anything ignoble to it either.
