I don't play GTA though even if I did your last paragraph is irrelevant to whether what you're saying makes sense (which it doesn't).
You're trying to say that playing GTA is a sin because Jesus said that fantasising about having sex with another person's wife is a sin and that somehow playing GTA means you have a desire (or will develop one) to actually go out and murder and rape (a groundless assertion if there ever was one).
The Jesus quote, as I said, is completely irrelevant. There's no evidence that GTA players fantasise about having sex with other people's wives or being more lustful or whatever. If you have it, do present it. If not, you're just moralising by taking Jesus out of context (when it's very clear what he's referring to - fantasising about comitting a sin is a sin)
And you can't assume GTA players fantasise about doing any of those things to real human beings (the quote says nothing about pixels btw and if anything, your idol analogy shows that it is you who is taking pixels to represent something real - a human being - as idolaters take pieces of wood or rock to represent something real - God. I am taking things for what they are - human beings are human beings and pixels on the screen are pixels on the screen).
As I said previously, all these are your unjustifiable inferences and not based in fact. You assume what you want to assume. So to repeat: there's no evidence that GTA players fantasise more about murdering or raping real human beings and that's the only relevant question here. If they do, playing GTA represents a temptation to sin for some people (although again, simply playing is not a sin). But you have no evidence for that.
and your scriptural reference to show your stance is based on the bible .. you forgot to add them perhaps?
we can have some nice sounding justifications and ideas on certain topics but the lord has said
"my thoughts are Higher then your thoughts , my ways Higher then your ways "
and consider the psalmist .. david asked
How can a young person stay on the path of purity?
and then he goes on to answer it
-By living according to your word.
10 I seek you with all my heart;
do not let me stray from your commands.
11 I have
hidden your word in my heart
that I might not sin against you.
12 Praise be to you, Lord;
teach me your decrees.
13 With my lips I recount
all the laws that come from your mouth.
14 I rejoice in following your statutes
as one rejoices in great riches.
15
I meditate(think on) on your precepts
and consider your ways.
16 I delight in your decrees;
I will not neglect your word.
so again we see the scripture is full of instructions on what we are to do in respect to how we
think and imagine
in the account of the tower of babel God destroys their tower ,for he states, .."that which they have IMAGINED in their HEART .. they will do ."
and it reaches an extreme in the days of Noah and God destroys all the earth for he Says... there is no longer any THOUGHT OF ME in them .
so over and over we see .. the principle is .. sow a thought and you reap a deed .
no my friend - there is nothing Godly in that Game it is filled with sin . it focusses the mind the thought and the imagination on every manner of thing that is an abomination in the sight of God .
