Another brutal dictator, Qaddafi of Libya, meets a violent end. Apparently he was killed in his hometown. Details are sketchy, but there is no question his end was grizzly.

As with Saddam Hussein in Iraq, Qaddafi was likely executed, but he didn't even get a trial. Those chasing him simply took him out.

All throughout history, terrible power-mongers have met violent ends. It's a karma thing. You cannot brutalize fellow human beings in any way and prosper.

The problem is guys like Qaddafi, Saddam, Hitler and Mussolini survived for far too long. In the end they got it, but along the way they did incredible damage.

The lesson over and over again is that there is evil in the world and always will be. That is the basis of many theologies: the struggle between good and evil. We all have free will. What side will we choose?

Hurting other people is evil. Helping them is good. There is no middle ground. You can't help on Tuesday and hurt on Wednesday. Harm always overrides any good one might do.

Qaddafi was a psychopath and a narcissist who couldn't care less about fellow human beings. He ruled Libya for an incredible 42 years before he met his fate.

The question is: How much responsibility does the United States, the world's most powerful nation, have when it comes to killers like Qaddafi, Saddam, the mullahs in Iran and other heinous people? The USA did not intervene when Hitler rose to power, and we've allowed other killers to rule as well.

Sadly, America can't really do very much anymore. The world is too complicated. Even though we're fighting evil in Afghanistan right now, many of the Afghan people stay on the sidelines and despise us.

The hard truth is we can't impose justice and morality on the world. Therefore people like Qaddafi are allowed to do their evil deeds for decades, but in the end they always –- always -- get what they deserve, either in this life or the next.

And that's "The Memo."

As you may know, actor Harrison Ford is also a pilot, and he's very interested in keeping airports safe. In order to do that, Mr. Ford wants to raise taxes on airline fuel:

HARRISON FORD, ACTOR/PILOT: I do think that the collection of taxes through a tax on fuel is the fairest and most expedient way to increase our funding.

(END VIDEO CLIP)

The problem with that is that it raises fares because the airline companies will pass along the costs, so once again the folks get hosed. The solution is to spend taxpayer money in a more efficient way. No more Solyndras. If Mr. Ford put that in, he'd be a patriot. But just calling for higher taxes at this point is pinheaded because the folks can't afford it.
