When will Sasuke realize that evil doesn't solve anything?

LOL. for one thing...he's not evil =p well n' my theory he will probably realize about da bonds btw3n him & NARUTO so he will eventually come 2 he's senses & not destroy KONOHA dat his bro loved & so dat way he & naruto will kill madara uchiha sumwhere away fr: da village & when dey do naruto will brin' sasuke home lyke he promise 2 sakura-i mean com on dere will b no naruto if sasuke dead
