You will have to choose whether to side with Mathis to kill Delgado or not during Echoes of the Past in Starfield. Learn about all kill Delgado choices, if you should kill Delgado, and when you can even kill Delgado.

All Kill Delgado Choices and Consequences

Side with Mathis or Reject His Plan

At several points during the Echoes of the Past sidequest, Mathis will propose that you take out Delgado when he's at his most vulnerable.

Even if you accept his plan to betray him, you actually can't assassinate Delgado since Delgado is not actually present after Mathis proposes his plan, and Mathis will ask you to forget about the assassination attempt entirely.

Your choice whether to accept or reject his plan, however, will affect your dialogue options for a choice later in the mission.

Tell the Truth or Lie About Mathis' Performance

At the final intercom before leaving the planet, you have the option to tell Delgado about Mathis' performance and whether he helped you or not find information regarding Kryx's Legacy.

Your choice here will affect Mathis' attitude towards you by the end of the mission, as well as whether you can recruit him as a companion.

Should You Side with Mathis and Kill Delgado?

Side with Mathis to Kill Delgado

If you choose to listen to Mathis' plan, he'll outline a plot to assassinate Delgado but cannot actually follow through with the plan. He'll eventually ask you to forget about his plan once you reach the final intercom.

Note: Although you can threaten to rat Mathis out, you actually can't reveal his plans to Delgado.

Reject His Plan to Kill Delgado

If you choose to reject Mathis' plan, he'll ask you to forget he mentioned anything. You can still threaten to rat Mathis out to Delgado, but you don't actually have an option to do so when you reach the final intercom.

Tell Delgado that Mathis Didn't Help During the Mission

At the final intercom before leaving the planet, you can tell Delgado that Mathis didn't help find information on Kryx's Legacy and he'll take your word into consideration.

If you tell Delgado that he made the right decision once you return to The Key, Mathis is kicked out of the Crimson Fleet. Later, talking to Mathis will lead to him swearing revenge and you'll randomly encounter him in space where he'll attempt to gun you down.
