2. an obsession with doing extravagant or grand things.

Chara is number 1. They want to be great by murdering everyone.

Sans is number 2. He wants to do something extravagent, despite not being able to: He wants to stop YOU. Another meaning is a delusional  mental illness that is marked by feelings of personal  omnipotence and  grandeur Which obviously relates to Chara
