[ All of this is maybe getting a little too philosophical for how drunk Koujaku must already be right now and Shinpachi knows it. But he also knows that people tend to get a little more honest when they're drunk, and.. well, it sounds like some sort of Issue is going on here. Maybe it's just something that's for the better if the other can properly vent it right now instead of cropping it up usually. ]

Define "bad". There's sometimes tough choices you gotta make where you have to do one thing bad so you can do good for another thing. [ Tell him about it, that's basically Shinpachi's life right there with his rigid ideals.. ]

And then there's people who do bad stuff without realising it, but try to make up for it later. I don't think I'd necessarily call either of 'em bad people or by principle not heroes, depending on the situation.
