But I really don't get why test it on your clan... Kishi should've added some more story into this. All we got was that Itachi wanted to test his limits, but that's a bit dull to me. Unless I missed some stuff.
Theres *probally* more to it then just him testing his limits but Kishi just hasn't put it in yet. But if he doesn't then it is dull imo.
Anyways id say Kakashi is cooler cause Itachi pisses me off and wears women clothes and paints his nails purple..
