Gollum is a Close relative to the hobbits who gets changed by the influence of the ring.
Bilbo said, talking to himself, "what have i got in my pocket?" (it was the Ring). Gollum thought it was a riddle and Bilbo decided to make it one. he gave Gollum three chances to guess and gollum lost after four. then gollum went "to get something" (it was the ring), and Bilbo thought he was abandoned and left with the ring on. Gollum thought Bilbo knew the way out and he wanted to follow him, realizing Bilbo had the ring. Bilbo saw Gollum racing towards the gate and followed him to safety.
Frodo realized how the Ring of Sauron was destroying him and his nature with less than a year of serious exposure and could empathize with a creature like Gollum who was once a Hobbit but had 500 years over which the Ring of Sauron destroyed him. Frodo's understanding of Gollum's pain derived from the Ring of Sauron is what leads to this pity.
