>>30609176Well maybe not that much but he went apeshit when he knew that team skull/Aether got their hand on cosmog and Lillie. At the very least he cared about Lusamine opening the gate(as he knew she need cosmog and warned MC about it before). Other reason he stole type null other than pure pity is because it is an anti-UB weapon. He even wrote the letter to Lusamine explaining how his action is necessary(to kill UB) and hope she would understand but never sent it (you can read it by talking to his apartment's owner post-game).
So let me redact my answer, yeah he want to be strong to prevent UB invasion, Lillie's safety is minor priority.
