I thought that what made a wolf a hero was if it had all positive vitals but I recently talked with someone and they said it didn’t matter if they had negative vitals as long as it added up to a positive number.

No. That's incorrect information you were recently given.

If there's a single negative value, the wolf is considered a neutral wolf, if it's all positive (not adding up to a positive number, all have to be positive), it's a hero. Coward wolves are all negative

Here's a guide to further explain heroes, cowards and neutral wolves

Thank you!
