I disagree a little on the issue of showing talent, for example: Minato would never have Jiraiya as a master and would not even have access to the hiraishin if he hid his potential.
We can accept the case for Kakashi and Orochimaru. But you have to take into account shisui and especially Itachi were very young and were brainwashed by the will of fire. Itachi was a kid when he was targeted by village elders, due to his immense talent. Itachi had to kill the clan or there would have been more deaths due to the uchiha civil war. As for haru, yes he should show case his talent to the village due to the massive support of the senju clan.
Leitor_Onisciente:Orochimaru and Kakashi weren't drawn into political battles until their late teens, Itachi and Shisui were just naive and dumb, who would sacrifice their kin for strangers?
