Chris (TDAS and TDPI), Sugar and the Ice Dancers are the only villains to get away with every bad things (hence Karma Houdini). Why?
 * 1) Chris. While he got away with trapping the eliminated all-stars in the fart balloon and destroying Camp Wawanakwa, his worst crime took place in TDPI. He made Shawn (with his confessionals) and Sky (her audition tape) look like dirt. He also got away with this motive (for now, since TD hasn't aired new episodes since 2014).
 * 2) Sugar being eliminated in her own trap (a talent contest that was won by Shawn and [taking second] Sky) was not enough karma, even for what she did to sweet Ella.
 * 3) Even though the Sisters and the Goths wished the worst of Ice Dancers, a flat tire (which could happen to anyone) and being forced to watch their enemies didn't seem suffice for their actions.

P.S. TVTropes ruined my life, learning that Sugar and the Ice Dancers got away with bad things. Chris didn't learn from his TDRI arrest in the later seasons.
