While it is true that the word "bot" can mean any program from first-person-shooter games AI opponents to harmless IRC bots, these are not used in the context of botnets(1) and thus irrelevant to our discussion(2).
Unless you want to try a valid argument for a change, I'm done here.

Notes:
(1) you can safely assume your Counterstrike bots won't take over your gaming machine
(2) effectively outside of the scope
since you're pulling wikipedia quotes i'll pull part of the same quote:
i agree that most are probably malicious
i disagree that 100% of them are 'inherently' malicious
