Laudna and Orym are not all that different, it seems.
Orym wielded Otohan’s sword to overcome the power it had over him and to become more powerful in the fight against Ludinus. He didn’t discuss his decision with anyone, nor did he think about how anyone else would feel, because he thought he was completely justified in his actions.
Laudna attempted to absorb Otohan’s sword to overcome the power it had over her and to become more powerful in the fight against Ludinus. She didn’t discuss her decision with anyone, nor did she think about how anyone else would feel, because she thought she was completely justified in her actions.
