Is anyone else disappointed with the High Maintenance trait?

If I understood correctly the death is caused by +5 angry moodlet from having a bad day and +2 from something else cause by the trait? I checked and it takes +7 for sim to become enraged. I like random death, but it seems a bit much that a sim would die (frequently) because of two pretty common moodlets from a single trait. I feel like there should be at least +1 angry coming from a different source before they reach the critical stage.
