Being fiercely loyal and a ferocious and brutal fighter doesn't make him savage.

That was more due to gross carelessness - part of it due to the fact that his vision was impaired during the undersea fight.

Savagery is untamed and wild - like a wild beast. Look at the Animated Dinobots, they will attack anyone that they perceive as a threat... Autobot, Decepticon, human... they are, generally speaking, indiscriminate. Unless there's a specific compelling reason, the Animated Dinobots will attack anyone that they perceive as a threat, be they Autobot, Decepticon or human - it matters not to them.

Noble/Savage was pretty much the same, with the sole exception of Nightscream
Rattrap: "Anyone order the fricasee rat?"

Thrust: "Any last requests?"
Rattrap: "Yeah, I like my Vehicons well done!"

G1 Slag is savage when he goes into his Berserker rage state - and the true definition of a Berserker from classical Norse/Old English literature states that a Berserker's fury is savage where he cannot discriminate between friend and foe.

G1 Slag did at least once kill an entire unit of fellow Autobots on Cybertron when he went into his berserker state - he nearly did it again when he went berserk during the Earthforce saga, but was thankfully "contained" (hehehe) buy his fellow Dinobots who desperately try to maintain Slag's dark secret.

Lugnut on the other hand is intelligent enough that he isn't savage. He discriminates between Autobots, Decepticons and humans - discriminates between friends and foe, regardless of knocking Blitzwing about. After all, even Starscream discriminates between friend and foe - it's just that he occasionally discriminates against his allies which of course has garnered him his treacherous reputation. When Starscream plots against Megatron, he's fully aware that Megatron is his ally. When the Animated Dinobots attack Autobots or Decepticons, they're not making the distinction between ally and enemy - they just see them all as mutual threats.

The Decepticons are all malicious in their own way. The Animated Dinobots aren't malicious. They attack others because they feel threatened, but they hold no specific malice intent or feelings towards other individuals. Being attacked by a Dinobot in Animated is like being attacked by a lion or crocodile... even when they attacked Meltdown on Dinobot island, it was a reaction to him having previously harmed them. When the Decepticons attack, it is most certainly with malice.
