Pretty much everyone in Corporate America dealing with Sarbanes-Oxley was affected by Lay's shenanigans.

Enron's downfall was caused by many people - Lay played his prominent role, but Andrew Fastow and Jeff Skilling were the guys who actually figured out how to game the system and they had plenty of enablers from Lay to complacent shareholders to aggressive accountants to Congress to capricious tax rulings.
Lay was just one of a whole cast of scummy characters.
