Bush wasn't a malevolent force? The man who lied us into a war against Iraq that killed hundreds of thousands of civilians, forced countless more to flee as refugees and gave rise to ISIS? A war that also transferred a trillion dollars from taxpayers to the MIC. The administration that also lead us into the worst financial crisis since the Great Depression? Bush and his administration were monstrous. The fact that Trump and this Congress have lowered the bar on how awful it is possible for a President and Congress to be doesn't absolve Bush of his crimes. 

And no, I am not some blind partisan who gives Democrats a pass on their crimes. Hillary and the DNC establishment are a corrupt as can be. Obama failed to prosecute the bankers, continued the wars and killed countless innocents with drone strikes. He didn't fight for single payer. We have two corrupt parties. Trump doesn't win without a Democratic party that is almost as bought off by corporate interests as the Republicans.
