The tadpole is a bad example of what you are trying to say.
You are not getting a choice over good vs evil in that situation, but you are compelled to beat the tadpoles psionic defenses if you want to kill it, the same as any other DC or saving throw in the game.
The tadpole isn't going to just give up without a fight.
In that case the only thing I wish is that failing the checks wouldn't damage your reputation with most companions.
Yeah, that's my biggest problem with some of the checks. A lot of times you take a double hit from both failing in what you want to do and taking the reputation hit. And while it's easy to make up reputation with party members who generally agree with you, trying to keep the assistance of ones that don't needs all the help it can get.
