Yes, the line of reasoning is the same.
It most certainly can be, and it is.
Correct.
Sorry if you are confused.
I'm not. The confusion belongs to you.
If you think God is only as powerful as a gun manufacturer then I think you missed a lot of Sunday School.
I don't make claim to that premise, so this is moot.
Incorrect. To explain why this claim is incorrect is to dive into a deeper discussion:
This discussion gets into one of numerous instances throughout Christian dogma in which an apparent contradiction is at hand. On the one hand, the Bible says that God is the sovereign creator of all things (which would include sin). On the other hand, the Bible says that everything that God created was "good" and that God abhors sin (thus God didn't create sin, which he abhors). If God didn't create sin, then did Satan create it? If Satan created sin, then sin would be beyond God's control (which also goes against what the Bible says). Hmmmmmm....
The answer to this conundrum is that the question that is being asked is based on an incorrect premise (that "sin is a created thing"). Sin is not something that is "made"/"created" (such as trees and animals). Rather, sin comes about as the result of a chosen rebellious action. Sin is a decision to pervert the good things that God has made.
So, it is incorrect to say that "God
made sin". Rather, God
permitted sin to come about via his decision to create celestial and earthly beings with free will (IOW, with the ability to hate/rebel against him, to deny his existence, to be indifferent towards him, to be indifferent about his possible existence, to regularly attend church but not truly love/worship him, to fervently love/worship him, etc etc). Allowing for celestial and earthly beings to make such decisions necessarily allows for the possibility of sin to come about.
God made humans, God made humans capable of sin.
This you have correct, but note that this does not mean that God made sin. It means that God allowed for the possibility of sin. Why? Because God wants his creation to desire fellowship with him (not to hate him or to be indifferent or lukewarm towards him), and such desire is impossible without having the free will TO desire (or to despise, or to be indifferent about, etc). Such desire for fellowship is no different than what you and I generally want for ourselves in our relationships with others.
Not so much. Colt didn't create violence.
Correct, but that's exactly what my point is. Just as Colt didn't create violence, God didn't create sin. Blaming Colt for violence is just plain stupid, and so is blaming God for sin.
(Again, Colt is NOT GOD. I can't stress that enough. If you can't differentiate between God and a Gun Manufacturer then your faith must be very very interesting).
You are stressing that which is completely irrelevant.
