If you really feel like you've done nothing wrong, why do you feel compelled to come to this forum repeatedly, inventing analogies to justify your actions?

In my opinion, the skill you possess to make undetectable repairs to items that have value comes with the responsibility to use that skill wisely, or in some cases, not to use it at all. You've ignored that responsibility by trying to compartmentalize your actions from the history of the chips you have worked on.

You can't isolate your actions from the chain of events that flow from them. You have direct responsibility for creating situations where fraud can occur. And, in my opinion, you were smart enough to have the foreknowledge that fraud was a possibile future consequence of your repairs.
