While it's terrible that this happened, Norway is going to enact stricter gun control laws after this. It shows that their system works infinitely better than ours, in which gun purchases accelerate after every high-profile mass shooting.
This is an incredibly sad incident all-around. But other than that (what should be) obvious thought that any rational human should have (you know, not DT or TheReckoning) I came to same conclusion as you did. Norway is going to embarrass us at how efficient and practical they are with how their government reacts to a horror like this.
However, also expect an uptick in xenophobic reaction to this as well, unfortunately. Even in the most cultivated societies you still can never completely avoid reactionaries.
