from the transformers wiki: While Orion Pax thwarted this, Sentinel's men were still able to discover that Senator Shockwave was quietly forming an army of dissident outliers. Sentinel ordered Shockwave's academy destroyed in an "accident" and Shockwave himself subjected to empurata and brainwashing.

In other words Sentinel Prime was ultimately responsible for ruining Shockwave's ideal into making peace.
