Do you think Judas Iscariot is really a bad person?

Did he really betrayed Jesus Christ?
I know that talking about this would be very sensitive.
And I don’t think he is bad or he really betrayed Jesus.
During the Last Supper (I guess after, not sure), Jesus and Judas moved away from 11 Apostles and had a conversation.
So I guess he (Judas) was only an instrument to occur the crucifixion.
p.s. I hope you guys understand my English.
