Wolf,
Putting words in others posts again? Did I say you said you had charoto?
But, if we have to parse what you did say, logic would dictate that although you did not have charota that you did it for your mother, you had no intention for the mitzvah. Which you seem to feel is pointless based on the snarky tone of your post. ( Wolf will now say “snarky? What? How can that be?”). So it would appear, from, logic, that there was charoto on the mitzvah, even if you didn’t have charotah for helping your mother.
But this only applies if you think about something logically. If someone’s words and actions are divorced from logic, one cannot make such inferences from their words or actions.
