I'm not entirely sure about this - yeah, sure, on one hand you have some negative feedback but it's just one guy. Admittedly this feedback makes me feel a tad unsure, especially since it calls to question your ability to roleplay a robot.
To end the debate as to whether or not a positronic brain (i.e an entirely intelligent being) would fear death - yes, definitely. A positronic brain would definitely be aware of its owns existence, consciousness, etc. and thus would want to avoid the end of that. Basically, yeah, it would have some level of self-preservation - maybe even enough to call into question the terms of its death before it happens in an attempt to stop it.
In short, more feedback, please! Cronac, I'd suggest posting this in OOC so more people would be aware of it - Unknown, your concerns have been definitely noted.
Terveiset, rrrrrr
