No. Neither of those are verbs. They're both nouns.

The subject of the first clause is "He." You'll find the first verb by asking, "What did he do?"

The subject of the second clause is "this." What does this do?
The verb would be suffered and causing? or is it just suffered?
Yes, the verbs are "suffered" and "is causing" because both are actions.
