This world is programmed to allow so called bad things to go unchallenged, if we're talking the classic definition of what bad and evil is and realize there is really neither, only contraction off and expansion off soul level connection, ie closer to and farther from source.
Its only in the movies where bad guys get chased down and either put away or the story kills them implying justice. In reality, you can steal, rob, harm and kill people, and so long as you know how the system is corrupt you will get away with it. The system is intolerant of stupid evil though, in order to get away with it you have to be smart too. Or at least be around some that are.
As blast says, it is easier.
Look at all the people in history that have found hundreds of ways to cure cancers and provide free energy to uplift the planet, they get murdered or otherwise destroyed, but at the same time governments, the un, who, fema, and other militaries are all sent in regularly to kill innocent people or to steal oil, or land or some shit and they get away with it time and time again.
Theres a lot of factors happening at personal levels but I believe one of the biggest is, its just easier. This world is and has been for sometime very inverted. You can't even smack people upside the head with the truth but they will believe a lie like its gospel, partially because it is spread like gospel.
