seriously,in akatuski,itachi is fear,and respected,even by pain.rember dat itachi fought madara once,n it ws draw,when he wntd 2 kill his family,but itachi said he will do it on 1 condition,dat is leaving sasuke alive,after all d fight and all,madara noticed dat itachi is too strong,so he left him.had it been madara stronger dan itachi,he would ve destroY konoha,but itachi said no,and all in atkasuki just obey.had it been he is not strong they would n.t listen,especially madara,so itachi may win
