from a truly neutral standpoint, you're both wasting words on pointless jeering  - although i fully understand the frustration of you both.

if i may, i would suggest that you stop trying to figure out the 'truth' and who is 'right', and instead, rule out a decision that would, to a certain extent, satisfy you both: such as both characters ending up taking moderate damage. the approach you're taking right now seems like it will never come to fruition.
