Am I The Asshole for saving the life of an evil person?

(Disclaimer: this is a joke post based on the characters from the Avatar movies, this is not a real AITA? post)

This whole thing is so screwed up that I don’t even know where to start. Sorry if this is confusing.

So a couple of months ago, I (16M) was captured by the clone of my crazy dead biological father and taken to the RDA to get tortured for information. I’m an orphan, so I don’t have any living family (other than my friends, who I consider my family, but they’re 14M, 14F, and 8F so there wasn’t really anything they could do) and I knew there was no one who would come rescue me. By the time they started interrogating me, I was pretty sure I was as good as dead. I even told the enemy that they would have to kill me before I would talk. But obviously I didn’t die or I wouldn’t be here writing this. The clone saved me. We made a deal that I would act as his guide and translator and in return he would protect me from being tortured and he wouldn’t make me give up any info. I spent the next few months in the jungle teaching him and his squad how to survive in the forest and I can’t believe I’m saying this but it was kind of… nice? I guess? I dunno maybe I had stockholm syndrome or something.

But anyways, it didn’t last forever cause he eventually got a lead on his target, who just so happens to be my best friends’ dad, and we went after him. The clone did so many horrible things. He set villages on fire, hunted an innocent tulkun mother and her calf, threatened to kill people, and I think the only reason he didn’t kill anyone is because I begged him not to. When he finally tracked down my friends’ dad, he and his soldiers ended up using my friends as hostages, and the worst part is that my friends’ older brother (15M) was shot by his right hand man when he helped me and 14M escape. After that, the clone was still holding 14F hostage, and he almost got my friends’ dad to surrender, but before he could, my friends’ mom grabbed me and took me as a hostage too. She was going to kill me to avenge her son, and I thought the clone was just gonna let her do it. Taking out my friends’ dad was the only thing he seemed to care about, but to my surprise, he let 14F go after their mom cut me. Thankfully, we were all able to walk away from that without anyone else dying or getting hurt.

Now here’s the part where I’m probably the asshole. After the big battle, I found the clone drowning underwater. I knew I should've just left him to die, I really really tried to, but for some reason I just couldn’t. I saved him. I guess I felt like I owed him or something. When he realized I saved him, clone called me his son and asked me to come with him, but I just hissed at him and ran back to my friends and their parents. I haven’t told anyone what I did yet. I know I need to tell them at some point but I just don’t know how. The clone was pretty beat up so I know he won’t come back anytime soon, but one thing I know about that bastard is that he doesn’t quit. He’ll be back at some point. What should I do? Am I the asshole?
