What are Toussen's intentions?

[Emperor Knives]

I'm still a bit confused with why Toussen joined Aizen and Ichimaru. Didn't he want the path with "less bloodshed"? Wasn't he the one who opposed the kind of path they were taking?

[VinScythe]

I always simply just figured Tousen wanted to gain power in order to actually carry out justice, and that came with Aizen's bargaining..

[Pyramus]

yea! but i would have thought justice is NOT sideing with evil!

[Nubaa]

yea! but i would have thought justice is NOT sideing with evil!

Obviously Tousen doesn't view Aizen as evil.

[TargaryenX]

He views what he's doing as "for the greater good". Sacrifices must be made.

[Jameslock]

Anime viewers don't know Aizen's plan yet, so I have to put that in spoiler tags...

To go to the King's territory within soul soiciety and kill the king, who is supposedly in charge of everything.

With this in mind, Tousen may believe killing the king they can rewrite the laws and enforce true justice.

My other theory would be that Tousen is simply using Aizen and is then going to stab him in the back to save the world.

[SnowManZero]

He said it himself when they were leaving the soul society.

"My[Tousen's] eye's can only see the path with the least bloodshed. So whatever way I choose is the right path."

He want's peace, and he know's that in order to get peace killing has to occur. So, he'll help aizen kill out all the bad people(In his mind) and create a utopia with Aizen as the leader and him as carefree as anything.

See, Tousen think's very highly of himself. We kinda will have a hard time seing thing's from his perspective-that is until we shove our head's up our asses.

[Geosuke]

aizen said it himself. once you SEE (or even have a glimpse) his Kyoka Suigetsu, you will be in total hypnosis.

does this has something to do with tousen's blindness/alliance to aizen?

[SnowManZero]

yep. it's the reason why Aizen scouted him to help him out in the first place. See if you can't see his hypnosis ceremony, then he doesn't have an effect on you. SO, in order to avoid any screw up's with his plan, Aizen coerced tousen into fighting along side him, probably when he was in the 5th division.

That way, with all his talk's on justice and blah blah blah he wouldn't be suspected (except for the fact that he's afraid to die, and even then he's only suspected by Zaraki kenpachi) of anything and could probably get around and do the legwork easier then gin-whom everyone hardly trusted, and aizen who was kinda looking dead when we start watching the main part of his plan.

Aizen's a smartass but a damn good one.

[Achilles]

yep, Aizen did well when he turned Tousen to his ally. he's blind and because of this he's the only person who don't get effected by Aizen's hypnosis power.
normally if you see Aizen's hypnosis power no matter what you can't avoid it.
