Gun Control..... ummm, no.

After watching a video on Youtube pertaining in small part to gun control, and then not being able to comment, due to an error on YT, I figured I'd vent here!
There are many arguments for and against gun control, but I want to focus on a generalized view of the whole thing. It seems, after reading comments on YT that many people who support gun control believe that an armed population is a dangerous population, as now, everyone has a gun, so crime will automatically rise, as will murders, because, as we all know, guns kill people (and rob banks, and conduct drug deals, etc.). This is a flawed argument, as it assumes that if carrying guns is legalized, everyone suddenly has a moral collapse, and crime in and of itself becomes acceptable.
The way I see it, criminals are criminals, no matter what. Sure, some can be rehabilited, but once someone goes down that road, it's hard to get off it. If someone is willing to break the law with a gun, what will stop them committing a crime by owning a gun? They simply ignore the law, and because of this, criminals will always find a way to get or own guns. So, by enacting any sort of gun control, the only people who will be disarmed are those who would not commit a crime with a gun in the first place. It causes crime to rise, as those who are the victims of crime have no way to defend themselves. Criminals will be emboldened as there is less of a chance of harm coming their way when the people they attack have no line of defense.
Granted, there are exceptions to the rule. By allowing everyone to have guns, someone who is mentally unstable is almost guaranteed to have easy access to obtain a firearm that they intend to use to slaughter a number of innocent civilians. However, on the flip side of this, if someone who is unstable goes on a rampage, similar to what has happened on countless college and school campuses in recent years, undoubtedly, someone else there will be carrying a weapon, and will be able to stop the carnage before it gets out of hand. It brings balance to the power having a gun brings. For every 1 criminal or nutjob who has a gun and decides to use it in an illegal manner, there will be 10 law-abiding, gun-carrying civilians who can stop them. I'm speaking in generalities, obviously, and there will always be bad apples on any tree. I just feel that if a bad apple comes my way, I should have the right to dispose of it, so it doesn't hurt anyone else.
