No Romans 9 does not tell us God unconditionally hated Esau (Edom)
Rather God chose Israel rather than Edom so that his purpose might be fulfilled
A 1000 years after Jacob -Esau lived it was stated
Malachi 1 (KJV 1900)
1 THE burden of the word of the LORD to Israel by Malachi.
2 I have loved you, saith the LORD.
Yet ye say, Wherein hast thou loved us?
Was not Esau Jacob’s brother? saith the LORD:
Yet I loved Jacob,
3 And I hated Esau,
And laid his mountains and his heritage waste for the dragons of the wilderness.
4 Whereas Edom saith, We are impoverished,
But we will return and build the desolate places;
Thus saith the LORD of hosts,
They shall build, but I will throw down;
And they shall call them, The border of wickedness,
And, The people against whom the LORD hath indignation for ever.
5 And your eyes shall see, and ye shall say,
The LORD will be magnified from the border of Israel.
6 A son honoureth his father, and a servant his master:
If then I be a father, where is mine honour?
And if I be a master, where is my fear?
Saith the LORD of hosts unto you, O priests, that despise my name.
And ye say, Wherein have we despised thy name?
7 Ye offer polluted bread upon mine altar;
And ye say, Wherein have we polluted thee?
In that ye say, The table of the LORD is contemptible.
8 And if ye offer the blind for sacrifice, is it not evil?
And if ye offer the lame and sick, is it not evil?
Offer it now unto thy governor;
Will he be pleased with thee, or accept thy person? saith the LORD of hosts.
9 And now, I pray you, beseech God that he will be gracious unto us:
This hath been by your means:
Will he regard your persons? saith the LORD of hosts.
10 Who is there even among you that would shut the doors for nought?
Neither do ye kindle fire on mine altar for nought.
I have no pleasure in you, saith the LORD of hosts,
Neither will I accept an offering at your hand.
11 For from the rising of the sun even unto the going down of the same
My name shall be great among the Gentiles;
And in every place incense shall be offered unto my name, and a pure offering:
For my name shall be great among the heathen, saith the LORD of hosts.
12 But ye have profaned it, in that ye say,
The table of the LORD is polluted;
And the fruit thereof, even his meat, is contemptible.
13 Ye said also, Behold, what a weariness is it!
And ye have snuffed at it, saith the LORD of hosts;
And ye brought that which was torn, and the lame, and the sick;
Thus ye brought an offering:
Should I accept this of your hand? saith the LORD.
14 But cursed be the deceiver, which hath in his flock a male,
And voweth, and sacrificeth unto the Lord a corrupt thing:
For I am a great King, saith the LORD of hosts,
And my name is dreadful among the heathen.
the reason being
Edom's violence again Jacob (Israel)
Obadiah 10–14 (KJV 1900)
10 For thy violence against thy brother Jacob shame shall cover thee,
And thou shalt be cut off for ever.
11 In the day that thou stoodest on the other side,
In the day that the strangers carried away captive his forces,
And foreigners entered into his gates,
And cast lots upon Jerusalem,
Even thou wast as one of them.
12 But thou shouldest not have looked on the day of thy brother in the day that he became a stranger;
Neither shouldest thou have rejoiced over the children of Judah in the day of their destruction;
Neither shouldest thou have spoken proudly in the day of distress.
13 Thou shouldest not have entered into the gate of my people in the day of their calamity:
Yea, thou shouldest not have looked on their affliction in the day of their calamity,
Nor have laid hands on their substance in the day of their calamity;
14 Neither shouldest thou have stood in the crossway, to cut off those of his that did escape;
Neither shouldest thou have delivered up those of his that did remain in the day of distress.
