You argue, in response to the idea that free will creates evil:
IMHO, this proposition carries greater implications that many realize. From this we must conclude that there exists no free will in heaven if free will is what causes evil and heaven is supposed to be "evil-free." Additionally, if we were to presume that free will can exist in heaven, then we can conclude that God is capable of creating an environment in which free will can exist without evil. If he is so capable yet an environment exists in which free will exists with evil, then we must conclude that God wanted evil there and in fact put it there, and the claim that free will is the cause of evil is thus negated.
Perhaps then we should restate the premise as, "Free will, as a part of a system for testing hearts, might include the opportunity to choose to create evil." Then, evil is the fault of those who chose to have that power, and was birthed out of their God-given free will with His permission. He, of course, knew what might happen when He gave such power, hoped (we suppose) that it wouldn't, but the choice to have or use such power does reveal a lot about what is in someone's heart, and so was consistent with His good will.
Meanwhile, free will probably does exist without evil, in heaven. To get to heaven, you have to hate evil, and pray "lead me not into temptation." That is, "don't give me the choice between evil and good." The only choices one chooses to have, are choices of good, better, or best, to sow abundantly or sparingly.
