Can politicians eliminate every act of evil and vice? They can pass laws but still not eliminate stupidity or ignorance. The can make it illegal to discriminate but they can't eliminate prejudice. They do not legislate on the basis of love or concern. They do it based on the emotional reaction of someone that has experienced an unfortunate event. It could be the loss of a loved one or losing their life's savings to a crook. They fail to account for the purpose of our existence when they legislate away legitimate choices. Yes bad people should be punished here and now but our system of justice is very imperfect. It can make criminals of honest citizens or criminals into honest politicians depending on the laws they pass and they have done so.
Looking from an eternal perspective we should see that our innate intelligence can only expand if it has some way of gaining experience. God doesn't just force it into us.
Experience only comes from actually existing (like we do at this present time) and then actually living somewhere (like this earth) where an individual can make choices and experience the consequences of those choices. Not only do we experience the results of our own choices but also the choices of many others that affect us positively and negatively. How we react to any of our circumstances is our choice.
If freedom is to be a part of our eternal existence then we must understand something of the laws that govern it. What so many people fail to grasp is the concept of eternal justice or eternal laws that govern our very existence and the process of creation. There are penalties that exist not because God is a vengeful god but because they exist independently and are immutable, meaning they will never change as natural law. The founders of this nation understood the role of natural law.
The law of gravity is easy to observe and the consequences of violating it are easy to determine. It's existence is also explainable when one understands the laws of physics. The idea that for every action there is a reaction or effect. So it is with our choices. They propel us forward or backwards in our progress through life. Each one has a power and direction associated with it, no matter how small it may be.
We pursue courses of action that we think will bring us pleasure and help is avoid pain. Of course we do have those laws in our society that restrict us from harming others. The real question is regarding the definition of harm. What does it mean to infringe on someone else's freedom?
