And Sasuke went back to the village, got married and had children. Say that his kid unlocks the sharingan and runs to Sasuke ecstatic with joy. Since Itachi implanted it so it would activate when he saw the sharingan, would he have killed his kid with Itachi's amaterasu?
"Look dad. Daaaaad. I have the sharingan finally.....YAAYYYY....AARAAAAAAGGGG. Dad what are you doing.....buuahhhaAaaarggggghhhhh"
Sasuke: "Uru sai"
