I liked this characters for 3 reasons.
1. These type of villians are needed to bring out hatred and move the viewers, or make us feel sympathy for the characters on the receiving end. It triggeres an emotional outburt, which makes this anime more memorable. 80%
2. When he turned into a weird ent like furry creature, I thought it looked kinda neet. 16%
3. Just to spite people lol (have mercy please) 4%
