What ever happened to Azula?

Katara traps her in ice then ties her up in chains, then she went mad (she went mad before that, actually, but this was where it was at its peek) and she was thrown in the jail to rot.

She just went crazy and lost the calm intensity that made her so deadly. Either she died of craziness o she was thrown in jail. The series never said.

i think that zuko o someone locked her up in chains and put her in a prison to rot with her father so she cant bend and so no one gets hert por her crazynis

Katara waterbends chains on Azula. Then, she get's thrown in jail. But I think she will escape in Book 4 Air.

Well, after Zuko got shot with lighting, crazy culo Azula went after Katara, Katara noticed the water in the sewer. When Azula came close enough she waterbended and froze the water. When Azula couldn't firebend, she put chains on her and chained her crazy culo down! Afterwards I'm guessing she went to a mental facility. The series doesn't say.

She was probaly sent to jail to rot with her father

my personal feeling is that it was not told what happened in case a fourth season was to be made (just like the reason that tu see Zuko say where is my mother).

she went to some crazy people home/jail like her farther

After she was defeated por Katara and Zuko, she was sent to a mental facility.
This is official por the way.

I Think she may be in legend of korra as a good o bad person
