The Bible says that people who don't worship the Judeo Christian should be put to death. Theres nothing in the theology of Norse Paganism or Hellenism which encourages religious wars. The idea that everyone else should follow your religion and you need to convert everyone else to it came from Judaism and Christianity.

Deuteronomy 13:13-15
'If you hear that in one of the towns, there are men who are telling people to go and worship other gods, it is your duty to look into the matter and examine it.'
'If it is proved and confirmed, you must put the inhabitants of that town to the sword.'
You must lay the town under the curse of destruction, the town and everything in it.'
Deuteronomy 13:1
'If a prophet arises among you offering some sign or wonder
and if he then tells you to follow other gods and worship them
'Do not listen to that prophet's words. Yahweh your God is testing you to find out if you love him with all your heart and soul.'
That prophet must be put to death. You must banish this evil from among you.'
There are numerous passages along the Bible along these lines.

The Christian persecution of paganism under Theodosius I began in 381, after the first couple of years his reign in the Eastern Roman Empire. In the 380s, Theodosius I reiterated Constantine's ban on Pagan sacrifice, prohibited haruspicy on pain of death, pioneered the criminalization of Magistrates who did not enforce anti-Pagan laws, broke up some pagan associations and destroyed Pagan temples.
Examples of the destruction of pagan temples in the late fourth century, as recorded in surviving texts, are:
Martin of Tours' attacks on holy sites in Gaul
the destruction of temples in Syria by Marcellus
the destruction of temples and images in, and surrounding Carthage
the Patriarch Theophilus who seized and destroyed pagan temples in Alexandria
the levelling of all the temples in Gaza
the wider destruction of holy sites that spread rapidly throughout Egypt.
These events I think had far more to do with the western Empire collapsing in on itself than the barbarians, as the Christian emperors effectively started a religious war against their own people.
