It's been a long time ago, but since this text is still nowhere to be found in romaji, I thought I might as well correct you here.
Genjitsu o miro. Kono yo wa omoidouri ni wa ikanu koto bakarida.
Open your eyes to reality. In this world nothing goes as you plan.
Nagaku ikireba ikiru hodo, genjitsu wa kurushimi to itami to munashi-sa dake ga tadayotte iru koto ni kizuku.
The longer you live, the more you realize that this reality is only filled with suffering, pain and emptiness.
(Nanda? Kono ji-ji...
What's up with that geezer...?)
Iika... Kono yo no subete ni oite, hikari ga ataru tokoro ni wa kanarazu kage ga aru.
Listen. Wherever there is light in this world, there will always be darkness as well.
Shousha to iu gainen ga aru ijou, haisha wa onajiku shite sonzai suru.
As long as there is a concept of victors, loosers will also exist.
Heiwa o tamochitai to suru riko-tekina ishi ga sensou o okoshi, ai o mamoru tame ni nikushimi ga umareru.
The selfish desire to keep peace initiates wars, and hatred is born to protect love.
Korera wa inga kankei ni ari, kirihanasu koto ga dekin.
Those things are each others causes and effects, and are thus inseparable.
For those of you who came here from MVs uploaded to youtube, their authors usually add some other quotes from Madara that aren't in this scene, most commonly something along the lines of:
Kono yo no... inga o tachikiru.
These... causes and effects. I want to sever them.
(also could be "This... fate. I want to sever it from this world.")
Shousha dake no sekai. Heiwa dake no sekai. Ai dake no sekai.
A world of only victors. A world of only peace. A world of only love.
Sorera dake no sekai o tsukuru.
I will create a world of those only.
Ore wa... Uchiha no boure~, Uchiha Madara da.
I am... a ghost of the Uchiha, Uchiha Madara.
