He needs a base of operations that he could construct in secret that was near his mansion. there was a cave in the nearby cliffside that barely anyone but him knew about so he went with that. it also helped that the bats that inspired his outfit also came from that cave.
The guy who was the inspiration for the movies Psycho , Texas Chainsaw Massacre and was the base for Buffalo Bill in Silence of the Lambs was Ed Geins. He was a serial killer from Wisconsin in the early 50's. After his mom died he went nuts and started killing woman. He would then cut off their skin, sew it together into a suit and wear it. He would walk around in it talking to himself in his mother's voice.
Eddie Gein was a shy boy growing up. His mother had very strong beliefs. His father was a drunk. When Ed went to school and tried to make friends his mother would punish him. Once there was a fire so his brother and father split up to put it out. His father became confused when his other son never came back. A few weeks later they found him with cuts and bruises on his head and face and neck. Eddie had killed him. He would take Woman parts of acuall people and put them on himself as of breast, vagina, and face. It was very disturbing! When he was young he really did invelope a intrest in chainsaws and torture. But no he did not kill all of his victoms with chainsaws. And he did kill more than 15 people!!!!!
