Such asinine logic. Since when should someone never do anything right if they can't do everything right?

Life isn't always going to be all or nothing. Like it or not, that's not how the world works. It's not all black and white. We should never, ever under any circumstances say that someone shouldn't do a good thing because they do bad things too. Sometimes you just have to take what you can get, especially because all change begins with one good step in the right direction, and if that step is met with clear and obvious approval from everyone it will encourage them to keep doing the right thing. If everyone has your bullshit apathetic and defeatist attitude then nothing changes, greed and corruption will continue to be the standard and slowly get even worse before anything changes for the better.
