Good. The path to evil should be easier and more immediately rewarding. Otherwise, no one but sadists and/or idiots would choose evil. Larian should be putting in scenarios where we really really want to use the tadpole, where it's incredibly difficult or maybe even impossible to complete the task otherwise at this time.* Like seen here:

*The "at this time" is important. We shouldn't be fully railroaded, but in this example you'll find SH later, so you're only missing out on approval, dialogue, and I guess an easier time of fighting Zhaik. None of this is a permanent loss of important content, so it's fine, good even.
