The more I play, the more I seem to only have options to encourage tadpole consumption. There is a notable lack of ability to roleplay my character, and even forced control in some instances.

For example, there's a dialogue with Lae'zel where my only 2 options are:
a) [Persuade] her that consuming tadpoles might actually be good.
b) Speak of other matters
There's no dialogue option to actually agree with her that tadpoles are bad, and choosing option b means that every time I talk to her, option a is prominently displayed again.

Even worse, there's a dialogue with another character. After (neutrally) bringing up the topic of tadpole powers, I was presented with not 1, not 2, but 3 different (simultaneous, not sequential) [Persuasion] dialogue options all of which were attempts to convince them that using the tadpole might be good. And ZERO options to say otherwise or even leave the conversation! I was forced to select one of those persuasion checks in order to continue with the game, meaning that now my character has advocated for tadpole use against my will. The only other option was to load an earlier save, but I want to emphasize that the original dialogue option---"So - about our tadpole powers..."---was neutral.

This extends to things not relating to the tadpoles. In a dialogue with the Gith in the Creche
Hatchery about taking the Egg
there are 3 different dialogue options to be Evil/Selfish/Greedy, and ZERO options to not be those things or leave the conversation. I was again forced to select one of them (or attack the NPC) to continue, and hope that I failed my check so that they'd tell me to go away.
