Let's recap what happened to her:

• The Rudra familia tries to murder Ryuu and everyone she cares about.
• Their failed trap unleashes a monster that turns everyone into minced meat.
• Ryuu is the only survivor; alone, abandoned, and nobody gives a shit about her.
• Her very goddess just leaves instead of trying to help her last "child".
• Neither the guild nor any other gods give a shit or even try to do anything about those responsible.
• She wiped out an objectively evil familia full of human trash of the sociopathic god Rudra.
• For some reason that's considered immoral and the Guild places a bounty on her, because wanting to avenge your familia and correct the grave injustice is considered "despicable", which is something even Ryuu herself seems to think.

I really hate this type of cliche writing so damn much. It's not deep, it's not interesting. It's another variant of "if you kill them, you'll become just like them". It's not only nonsensical in Ryuu's case, but there is not one single reason for Ryuu to not be fully justified in her actions.
She might lament that she was reckless in her actions and gambled with her life which her familia tried to save, but she would never lament that what she did was despicable. The world is objectively better if she did her purge. Anyone who says otherwise should blame the guild and the other gods for giving no firm response to the incident and letting the other familia get off without any real consequences.

I guarantee you that if something like that happened to Bell, he'd become anime Kratos as he's far more emotional than Ryuu is, but because it's Ryuu she needed a sad backstory with a PTSD.
