Gah, this is not too different from trying to blame your genes for something "my genes made me do it!!"
Your genes are part of what makes you, you. You cant seperate the two.
Exogenous test, well technicaly its something non essential youve introduced to your body. But once the test is in your body, its part of you. If you injected self-willingly, you cant blame test for any actions you do. You did them. And "you" includes every biological part of, well, you.
Slightly different story if the test was injected without your knowledge or approval. In that scenario you have another significant causal agent who is potentially complicit in any wrong sh1t you may do.
But, to take this to its logical extreme: food, air, water keep me alive. Are they then to blame for any actions I do whilst alive?
