Just beat Raidou 2 and I feel like I played a very different game from everyone else because I don't understand how the common consensus is "dahn was based and law was shit".
Dahn was a petulant child whose entire plan was flawed from the start. He's rebelling against a dying system and attempting to secure an utterly pointless future through the deaths of thousands. (End of game dialogue literally says no one needs assassins anymore so the clan's role as fukoshi is on the verge on collapse. Realistically in the near future they would have to give up and find proper work, rendering the needs for continued assistance with the tento or a stock of insects null.)
All while he's fully aware of this AND the person he's most intent on saving explicitly tells him to stop. And then what? We're supposed to sympathize with him when it all goes to hell because this fate entailed *more* genocide than he initially intended?
Now granted by the same token one could argue law at this point in the story is similarly inept but at least the suffering here was minimized. Unlike Dahn, Akane accepts that this fate is unappealing but acknowledges not resisting it generates the least amount of pain. I can respect a man's desire to prevent his sister from being a bug sex slave but everything Dahn did was wrong. He almost borders a lunatic, preaching and acting on extremely dangerous delusions.
Beyond the marriage ritual though, law is mostly just an ideology of basic complacence. Sure that isn't always the best way to live life but in no way is it bad. Akane even brings up an example concerning careers that's representative of most people today. How many of us aren't chasing our dreams because we'd rather stay in a job that's easy or secure? There's definitely extremes here but this isn't like most SMT where law is promoting some mass calamity. I don't see how you could walk away from the game thinking the law choices past the ritual were anything other than a respectable view on living.
