You can blame WAU, but it's like threaten bot that killed you in-game. Is this bot fault or programmer? Or maybe corporation that forced programmer to do this according to thier needs? Or maybe your's, cause bot's actions were actually response to your's? I say messing with nature-related matters is always risky. It's easier to clone someone than rethink whole chain of consequences. Creating complex AI (or any simpler program) might be risky. Malware are example.
I'm not telling you can't have bad feels toward WAU. I personally don't approve it's actions. But it's kinda matter of preserving humanity by all cost or accepting death. It's everybody's opinion. And I love when folks have different feelings, that makes world less flat
The more I dig into SOMA story the more I like it.
