Query (Rich as they are, I think they shouldn't do that.)

[Nessie]

Hi, please have a look at this:

Rich as they are, I think they shouldn't do that.

=> Does the sentence sound natural? or should we omit the phrase "I think"?

Many thanks
Nessie

I don't feel there is any necessity to rule out 'I think' but of course it can be taken away.

The sentence is natural with or without "I think". Inserting those two words just softens it to mean, "In my opinion they shouldn't do that."
