Step one of anger management — Don't

Lucifer now really wanted to smoke, but alas he was on a mission. He was watching Isadora with his mask on and recording. The assassins could not sense him, but he knew where each one was — but there could always be more.

He could always surprise the assassins, but if there were other assassins only to observe from the distance, his master's plans would need a redrafting, and he was not here to fail his master.

The current plan was to wait and oversee Isadora's fight, getting anyone who acts suspicious at a distance, if all goes well — Lucifer will once again approach Victor in order to completely eradicate the assassin gathering with the help of the legal authorities through Detective Hawke. But if it doesn't, then getting through the organization would be even more of a pain since they would now be alerted against Lucifer's organization as well as the authorities.
