What about Judas Iscariot?

Ok i was never able to finish my post because of a limited number of words to write here (I guess). Judas was one of the disciples of Jesus and he went wherever Jesus went, he shared moments with Jesus in his life. Then came the betrayal. Jesus knew all along that he was gonna die because it was the plan of the Almighty. One thing that really surprised me as the story went was the betrayal of Judas. God did planned that for sure and he created Judas for the sole purpose of betraying Jesus which led to the crucifixion so men who believed in Him will be saved. But what about Judas? Will he go to hell because of what he did, or what he was designed for? Again, I'm not trying to tell anybody that God shouldnt have done that. But a lot of of people are questioning Him because of that alone. There are a lot of stuff that i read from the internet and I have read some saying that Judas was a hero because if it wasn't for his deed, mankind will not be saved. Others hated Judas because of the betrayal. Now I ask, to those who hate him, will they hate God when the heavens open at the judgement day and they see Judas sitting in one of the seats in Gods throne together with the disciples and other holy characters or hate him also if they saw Judas burning in hell after he has done his pupose? Well, this is just a mental itch, i am christian, only.... well.... I have no intentions to challenge one's faith, or rethink the belief. It's just a mental itch that needs to scratched. :)
