Why do politics turn to violence?

This question is very much suited to what we have this year in the Philippines. The upcoming elections had been very controversial because of the celebrities running for certain positions and other issues being brought up in connection to them. This got me thinking how dirty and disturbing politics is. Everyone seems to be wanting something so badly that they are willing to do anything and everything just to get it.

What do they do when they want something? They turn to violence. There have been reports on extra judicial killings and other government related killings in the past years. These had been thought of as to benefit some people. Some think that it would be for the government, to avoid other controversies that may affect its power. Some think it is for some important person only that is very much influential that his favor is important to some powerful group of individuals. Sometimes diplomacy is not an option when it comes to complicated things. And it looks like some politicians see violence as something helpful.

It is hard to stop all these killings. It straddles more on the morality of the people. I think the Church has to emphasize morality more especially now.
