He made it more likely by going it alone (although with Gomey). Had he employed the proper channels, the full force of the DEA could have come down on Walt. Hank valued the credit/his job more than his own safety. In the end, it was a poor gamble in a deal with someone that he knew to be as dangerous as Walt.
