Lately, with the manga veering off from the anime, a lot of confusion has been going on discussing the Sins, Hoienhemm, and various other FMA things.
Since I do not work on the anime production team, I can’t tell you what’s going to happen.
But I do have the manga, which is ahead of the anime. And give you all the info on it.
Let’s start with the sins.
Yes, Hoeinhemm created the Sins. And is Ed's father. And is still alive. He is in a labrotory where Manga!Wrath brings back Greed, and finds Gluttony, Lust, and Envy waiting for him.
This is manga sloth. Much different then the anime Juliet Douglass Trisha Elric Lookalike!Sloth. He's actually not there, but is rather chained up, or digging towrds something. Maybe a mixture of both, but this is speculation, and I want you all to know the facts.
Now, in the manga, there is never, ever, ever, ever, mention of the Sins being centuries old. Their ages are never mentioned. With Hoienhemm being pissed at Greed for going against his wishes, he decideds he's had enough of Greed, and destroyes him the only way he knows how.
Yes, he melts Greed. Once Greed becomes a yummy wine like center, Hoienhemm dose the next step.
He drinks him. Now, since all the Sins from Hoienhemm, the Sin "Greed" has now returned to Hoienhemm. That opens up a spot for another Greed, or no more Greeds.. *cough* Hughes *cough* But that's speculation for you all. :D
Now, wait a second. What's he doing here, you might ask?
Yes. Let me stress this. MANGA FUHRER IS WRATH. PEOPLE ARE NOT INCORRECT, LIKE SLOTH (But not to the same extant) ANIME SINS ARE DIFFERENT.
Now that certain comment is off my chest, I just wanted you all to know this info on the Sins. The manga is very different the the anime. It's changing, please, although it's spoil, keep this in mind. It'll help you with further FMA fandom. Now people don't have to constently remind people that little kid isn't Wrath in the manga.
^_^ Sorry if I came off rude.
