What did Bloodraven Try to Change in the Past? (Spoilers Extended)

After beginning his training with Bloodraven, Bran begins seeing visions of the past, resulting in Bloodraven telling him:

"He heard a whisper on the wind, a rustling amongst the leaves. You cannot speak to him, try as you might. I know. I have my own ghosts, Bran. A brother that I loved, a brother that I hated, a woman I desired. Through the trees, I see them still, but no word of mine has ever reached them. The past remains the past. We can learn from it, but we cannot change it." -ADWD, Bran III

This quote shows that Bloodraven has not only tried to contact those in his past, but has failed at changing it.

Knowing what we know about Bloodraven, what do you think he was trying to change/accomplish when contacting those in the past?

#Bloodraven Wiki page

• albino born from House Blackwood (old gods) and House Targaryen with a "raven" wine colored birthmark

• rivalry with Bittersteel

• sent to the wall by Egg

• sorcerer/greenseer

• loved Shiera Seastar

• has Dark Sister

• has/had a dragon egg

The list goes on and on.

Bloodraven disappeared on a ranging in 252 AC (after being the LC of the NW for 13 years) and before that was involved in several Blackfyre Rebellions, a Great Council and was Hand of the King. He's anti Blackfyre, pro Targaryen, anti Bracken, pro Blackwood.

So the question remains, what did he try and change? Sure it could be some small personal stuff (his love of Shiera, etc.) but with Bloodraven's history and knowledge and new power (and most likely part in what is really going on) seems to show that it is probably something bigger.

Please let me know what ideas you may have!

Possible Options

• Not killing Bittersteel after the Third Blackfyre Rebellion (he was sent to the watch instead and escaped back to Essos)

• Blackwood v. Bracken feud (helping his family in their feud with their rivals, possibly against Otho Bracken, that said this woudn't involve his brothers or Shiera)

• Beheading Aenys Blackfyre (Aegon V let him choose the watch over death)

• Something to do with sorcery/Shiera (he learned something beyond the wall that he could have used)

• Messing up the Euron Greyjoy situation somehow (whether he messed up Euron's mind, or Euron left, etc. is still up for debate, thanks u/Akkkkkermm)

TLDR: What was Bloodraven trying to accomplish by contacting those in the past?
