Bonecrusher is a Transformer that can be described with one word: Hate. While other Decepticons get by on greed, ambition, or just their fondness for dispensing chaos, Bonecrusher is fueled by sheer, unrelenting hate. He hates everyone and everything, be they Autobot, Decepticon, or anything in-between. This full force of this vicious cycle of hatred finds release in explosive frenzied bursts of psychotic brutality, as Bonecrusher takes out the full force of his bitterness and self-loathing on anyone who looks at him sideways. He also hates Megatron, but would hate being terminated (literally) by the Decepticon leader more, so, he sticks around.
