@Cheesecakehunter: I actually was pretty disappointed HK-47 wasn't a bounty hunter. But technically he and IG-86 just kill who they are programmed to, while IG-88 became a sentient being and hunted people for money.
But yes the snapshot tag explanation is flawed, and that was the main purpose of creating this post. I dont expect CG to be perfect but it seems like they tend to make arbitrary decisions about certain characters making them less fun for fans, even though fandom is supposed to be one of their guiding influences.
