All valid points, but Jade brushes them aside, not about to let go so soon now that he's found a point of vulnerability.

"Why?" He counters, as casually as if they're having a regular conversation. He smiles at Shinjirou indulgently, red eyes glittering. "Someone should, since you seem to have little interest in caring for yourself."

It's not entirely an exaggeration. Shinjirou had demonstrated a reckless lack of regard for his own life so far, and that's even without considering how pliant he is when the right leverage is applied. Honestly, it's a miracle that nobody had taken advantage of him before before Jade had.
