Why is Jerry Manthey considered a villain on Survivor?

Jerri Manthey was first considered a villain on Survivor: The Australian Outback. This was because she was often involved in conflicts and arguments with her fellow cast-mates.

Most notably from that season, was when Jerri accused Kel of eating the beef jerky. This caused a tiff between the rest of the tribe who was starving. She also went through his bag in search of the jerky, but did not find any evidence that Kel had taken it.
