No totalitarian regime should ever possess nukes or any weapon of mass destruction for that matter. Totalitarian regimes take actions based on the impulses of a single person, and nukes can destroy the world. Destroying the world should be a committee decision at the very least.

You are right, I was unclear. Since the topic is psychopaths I had that "subcategory" of criminals in mind. I'm talking about people who kill for the sake of killing, not people who do it out of desperation.

That said, I don't think your examples are very good. Policemen don't intend to kill in the line of duty, they intend to incapacitate criminals and prevent crimes. They are aware of and may be okay with the idea that this might kill the criminal, but that is not their main intent. (If it is, they are psychos and should be dealt with as described. ;))

Similarly a person who kills in self defense does not primarily intend to kill, he intends to protect himself. The only category of people who can legally intend to kill are in the military, and even then only during war.

Anyone who kills another person intentionally is insane. Any rapist is also insane. In my opinion it doesn't matter. Cold-blooded murderers and rapists need special treatments, for the good of society. So for these crimes I propose:

Whether the behaviour is caused by genetics or experiences or whatever else, a society should deal with this efficiently. Remove the offenders from society, publicly and permanently, so that this becomes a social incentive for other potential criminals. Add the threat of severe punishment to the "soup" of genes, experiences and whatever else causes a behaviour. It might help.

Even if it doesn't help, the ones that already have committed the crime and proven themselves to be (voluntarily or otherwise) a threat to society are put away so they can't commit crimes again. They also can't spawn or traumatically raise more people who might also be more genetically and socially inclined to commit these types of crimes.

As an added bonus, the relatives of victims might feel some slight comfort and be able to move on in their own lives knowing that the creep that ruined their life is gone for good.

If genes makes someone a serial killer or rapist, he had a tough break in life but it should not matter in a criminal trial. If they caused him to be a kleptomaniac he will get help, but not when his disease causes physical and emotional trauma in other humans. These others have a disease as well, caused by him, so he has to go.

Consider this:
Governments are funding oil exploration and new oil wells, at the same time as they are increasing the tax on car fuels, adding congestion taxes and whatnot.

In other words, they are pumping more and more oil from the ground, and making sure that the sheep that voted for them are paying the maximum possible for each drop!

Why don't they help the environment for real by closing oil wells, or making it cost-prohibitive to extract it? Oil that isn't extracted can't be burnt!

Every drop of oil in the ground will be burnt, the politicians are not trying to stop it, they are just arguing about the price.

Likewise, ethanol exists as an alternative fuel only because there is money and votes to be made from it.
Using ethanol as a car fuel the way it is done today is WORSE for the environment than burning oil. But claiming otherwise sure sells a lot of new "green" cars, and you get a fine-looking reason to put extra taxes on anyone who can't afford one!

The politicians and corporations have suckered millions of people into "upgrading" their cars to monstrosities with abysmal mileage compared to other alternatives, and it has absolutely nothing to do with wanting to improve nature. I am glad that this scam is finally starting to fail.

Just as I thought the entire world had gone crazy, a small glimmer of hope! The genuine care for the environment that people have is being made into a religion, with a hierarchy of money grabbing priests and cardinals in every political party...tax this, tax that - level the forests, just pay the tax for it!
Somebody is actually selling the right to create carbon dioxide...it is so stupid I can't believe it is really happening.
Toxic waste pouring into rivers, whaling, levelling the rain forests - these are real environmental issues that have completely disappeared from the agenda because of this windmill of a problem, the huge money-circus called "global warming".
 
I fear that when people wake up and realise how they have been fooled, if they ever do, environmental causes will suffer for generations.
