From a position that is probably further left than most then you possibly do see Labour corruption as a bigger problem than the Tories, but that is based on what you want the Labour Party to be, which may be different to what other Labour supporters want it to be.
Labour it seems is doomed to the eternal battle for its 'soul' when faced with the fact that most people see only two credible alternatives for government and those on the further left or right of the party are too frightened, or pragmatic, to have the courage to split and form their own party. The Social Democrats tried that in the 80s but failed, imo, because too many Labour supporters were conditioned and/or lacked the vision to see that Labour did not have to be the only alternative to the Tories, and the far left would never have the courage to set up a stronger left wing party because it would be electoral suicide.
We get the parties and the governments that we want and thus deserve.
