Sid may attack you, depending on how you let him out.

Interactions overview
Attack.

Effects of player actions
If you free Fawkes by activating the lab's emergency fire systems, this will open all the other isolation rooms, freeing both Sid and two Centaurs. Although both are hostile towards you, they will also attack each other if they spot each other before spotting you.

If the door is unlocked by lockpicking, Sid is friendly but uncommunicative, screaming:
 * "No! It's all over me! I can feel it... it's invading my mind"
 * "Get out of my head! Get the fuck out! Aaaaagh!"
 * "Can't you see?! They're all dead! It's all my fault!"

Appearances
Sid only appears in Fallout 3.

Behind the scenes

 * In the construction set, there are dialogue options explaining that he killed all of the people in his isolation room and that he might have been captured by Super mutants.
