What is the exact purpose of the infinite Tsukuyomi?


What is the purpose of the infinite tsukuyomi, is it to make everyone dream in
their ideal world? Then why does it turn people to white zetsu and steal their
chakra?




The infinite tsukuyomi was actually a ruse by Kaguya, executed by black Zetsu,
who manipulated Madara.

Kaguya, the origin of all chakra after eating the shinju fruit, became power
hungry and was subsequently sealed up by her sons, who then went to
distribute/teach the usage of chakra to the rest of mankind. However, through
black Zetsu, she was able to manipulate mankind (namely Madara) into
recreating the infinite tsukiyomi with the Eye of the Moon plan. In doing so
she then would be able hypnotize everyone and reabsorb all of the chakra in
the world which she deems "rightfully hers."
