I think Hashirama would be just as pissed off as Tobirama. Think of all the things he's about to find out:
1. Not only did Madara fake his own death at the VOTE, but he also obtained some of Hashirama's DNA and...
2. Madara proceeded to implant this DNA into himself to gain the Rinnegan. Of course Madara wasn't the only one...
3. Orochimaru ended up implanting his DNA into not only Danzo, but sixty abducted children, only one of which (Yamato) survived. And finally...
4. His DNA was also cultivated to produce more than 80,000 White Zetsu clones that have been used in war to help kill a reported 40,000 Shinobi.
Quite a legacy there... :T_T:
