Why didn't Frodo just give the ring to Gollum?

[Knight of Gondor]

Dark Elf...please don't take insult in this...but that's kind of a moot -- silly? -- question. Of course Frodo wouldn't want to give the Ring to Gollum, his ultimate aim was to destroy the Ring! Perhaps if he were only concerned for his own selfish fate, then he might give the Ring to Gollum or someone else to jump ship and save himself. But that wasn't who he was.

Plus, he took pity on Gollum, and to give it back to him would be like turning a druggie you're trying to reform right back over to his drugs.
