Bruh, no way. The series has General Grievous who killed countless clones and wiped out Asajj Ventress's clan. He is not Pure Evil because Clone Wars is part of both the Legends and Canon universe, the former where Grievous has a tragic backstory. He has also some comic moments, and it is a war, where mass deaths are expected. Grievous has nearly killed Jar Jar and has come close to killing Obi-Wan Kenobi, and he nearly killed Ventress. Overall, he is worse than Tamsom, and still not Pure Evil due to the standards of the series.

It’s the same with Darth Maul. Maul has done very heinous acts like killing Satine Kryze, Obi-Wan's love interest, and conquering Mandalore and installing a ruthless regime. Still not Pure Evil because he loves his family a lot, and would never betray them. It’s also due to the standards of the series.

Want someone way worse than those two? Palpatine himself.

With all of that said, no, Tamson is not PE.
