と考えていい ending sentence meaning?


In Season 2, Episode 3 of Shingeki no Kyojin at 12:30, I encountered this
sentence:

[code]

    その表層は硬化した皮膚で形成されていると考えていい
    
[/code]

I understand its meaning literally is: "I think that this surface is
constructed by harden skin."

But I searched everywhere and can't find と考えていい used anywhere. What is the
meaning of adding ていい? is it a little redundant? Thank you.




I would translate と考えていい as: "You can think of it as...". It's like a shorter
form of 〜てもいい.

Your given sentence would be something like:

[code]

    "You can think of that surface as being molded/formed from hardened skin." 
    
[/code]
