Do anda believe Sekia is a bad person?

Sekia set up Kotonoha and Makoto then mencuri him. She did all this behind Kotonoha's back. She told Makoto it was just pratice to help him with Kotonoha. Then she started dating him and Kotonoha started going insane (when Sestuna forced Makoto to break up with her IT MIGHT NOT HAVE BEEN BEST but Makoto only needs one GF but it was Kotonoha who he should have just loved). Then Sekia pretended to be prego to get Makoto's attetion, when he went back out with Kotonoha. Then Sekia killed Makoto becuase she was no longer dating him. Causing Kotonoha to go insane.
