That's the same as thinking everything a Cleric does is good because the Cleric's god is good. That's isn't how things work. The Druid is availed a set of powers from nature. This does not make anything they do with those powers natural. If they were to kill a lot of wolves, for example, that would greatly upset the natural balance of the ecosystem. It would be unnatural. Similarly, going around Awakening animals for shits and giggles would mean greatly altering the animals from their natural state. They might as well be fusing owl heads to bear bodies. It is not the kind of behaviour a Druid, a protector of the natural balance, engage in. It is the behaviour of wizards and mages who enjoy fucking shit up for shits and giggles and don't give two damns about the consequences of their actions.
You're applying motive to the powers now though, and that wasn't a part of the original discussion.
The ability to awaken animals could be misused, true. But it can also be used in service to nature, which is how a druid would use that power. Awakening a wolf so it can lead its wolf pack more efficiently in the face of human hunters and to serve as a steward of the forest, as an example, is a completely druidic thing to do. Or awakening an owl that has become the druid's companion so they can work with the druid in their duties of safeguarding the lands more carefully.
If a druid were abusing their powers the way you describe they'd probably lose those powers. They operate like clerics in that they get their magic from a divine source and, as such, can lose that power if they use it incorrectly. And at least in older editions if they wore steel armor or changed alignment from neutral they ran the risk of losing their abilities just like a cleric who has forsaken their god or a paladin who broke their oath.
Now, because their patron is nature itself there's a lot more leeway in how to interpret what nature wants and needs. That is how you get shadow druids who believe they serve nature's will by bringing ruin to civilization. How far a druid has to go before they stop being able to awaken animals would probably be up to the DM.
But the power, in and of itself, is perfectly in-line with druids and how they operate. And if they are using their nature-given powers to better fulfill their role as nature's guardians then making an intelligent bear isn't a crime against nature.
