Do to them as you did to Midian,
as you did to Sisera and Jabin at the river Kishon,
10 who perished at Endor
and became like dung on the ground.
11 Make their nobles like Oreb and Zeeb,
all their princes like Zebah and Zalmunna,
12 who said, “Let us take possession
of the pasturelands of God.”
13 Make them like tumbleweed, my God,
like chaff before the wind.
14 As fire consumes the forest
or a flame sets the mountains ablaze,
15 so pursue them with your tempest
and terrify them with your storm.
16 Cover their faces with shame, Lord,
so that they will seek your name.
17 May they ever be ashamed and dismayed;
may they perish in disgrace.
18 Let them know that you, whose name is the Lord—
that you alone are the Most High over all the earth Psalm 83:9-18

When I was a young Christian, hanging out with the man who led me to the Lord and discipled me, it was common for Christians to look forward to the judgment of the wicked with a sort of “you deserve it” kind of heart. He took me to this passage in Amos:
Woe to you who desire the day of the LORD! For what good is the day of the LORD to you? It will be darkness, and not light. … Is not the day of the LORD darkness, and not light? Is it not very dark, with no brightness in it? – Amos 5:18, 20 NKJV
It breaks my heart when I consider the future of the lost.
