Stay because there is are potential upsides to staying and because those potential upsides are attractive relative to your alternatives. If there's an attractive potential upside to staying through a Series A, then stay because there is an attractive potential upside. That's not staying to 'help'. That might be an increase in value of your equity. But it's probably not going to entail much that isn't already in writing...so to speak.

To me, I doubt you can fix the situation. The founders have to desire to change the culture and make doing so a priority. If people walking out en masse doesn't inspire such change, then it ain't likely to change.

Good luck.
