Athiests, evolutionists, and the like delight in mocking God as a bad designer because mankind sins. If he had made us perfect, then we couldn't sin.
This argument crumbles when applied to anything else. Which reveals what a fallacy it is.
For example, a knife could be a perfectly designed instrument for chopping vegetables, but also capable of killing someone. Does this mean there is a flaw in the design of the knife? Was the designer of the knife an idiot for having made this tool with the side effect of being a weapon?
In much the same way, by making humans a perfectly designed instrument for having a relationship with (freewill), they are also capable of sin.
Of course you atheists cannot believe freewill exists. It is not possible for you to believe in freewill and have any sort of consistency in your philosophy. Freewill requires a force outside of the laws of this universe in order to be enacted.
