Yes, in the Five Nights at Freddy's series, it is heavily implied that William Afton, also known as the Purple Guy, built the animatronics with the intention of using them to kill and harm others. Afton is depicted as a sinister and malevolent character who uses the animatronics to carry out his dark deeds, and his actions are a central part of the game's lore and storyline.

Additionally, the animatronics may also be acting out of a sense of self-preservation, as they have been programmed to protect the pizzeria and its secrets. This creates a sense of tension and fear for the player as they try to survive the night while being hunted by the animatronics. **

The true names of the animatronics in Five Nights at Freddy's are Freddy Fazbear, Bonnie the Bunny, Chica the Chicken, Foxy the Pirate Fox, and Golden Freddy.
