When it comes to ruthlessness, Lyca always knew she was second to none.
Because of her laziness, she tends to kill people immediately. Not giving them the chance to scheme against her and disturb her peace. This was the reason why she mostly killed those clan heads in their territory. Lyca wasn't some hypocrite. She knew she was a sinner. She also knew that the reasons why she kills people are somewhat dense.
Sometimes, she killed them because she became too irritated. Sometimes, it was because she was too lazy to reason with them. Sometimes it was because they did something terrible and she didn't like it. In the end, her reasoning had something to do with her lazy nature. She just got lazy and decided to end it.
However, unlike Lord Olfan, Lyca never killed people for fun.
