Attack on Titan: What is もしくは doing in this comparision


I saw this sentence in an episode of Attack on Titan

> ライナーができないと言うように **もしくは** ライナーでさえここで休まざるを得ない現状を鑑みるに

The speaker is referencing something that ライナー said they can't do

I don't understand why you would use **もしくは** in this comparison I thought
**もしくは** meant A or B representing two different states but in this example
the two states to me don't seem that different

My translation would be

> ライナーができないと言うように - As\like Reiner said I cant do it
>
> **もしくは** - Or
>
> ライナーでさえここで休まざるを得ない現状を鑑みるに - I need to keep in mind that in this situation
> even Reiner was forced to take a break

What am I missing? To me it feels off as the second state seems to "agree"
with the first




The context seems significant in this case. I _think_ the lines mean something
like:

> だが、そもそも俺はまともに巨人化できるのか？  
>  But am I even able to properly transform into a 巨人 to begin with?
>
> ライナーができないと言うように(なるかもしれない)  
>  Things will likely go as Reiner said, which means I will probably fail (if
> I try)
>
> もしくは  
>  or
>
> ライナーでさえここで休まざるを得ない現状を鑑みるに  
>  Judging from the fact that even Reiner has to take a break here
>
> 下手に体力のない巨人を生み出せばほかの巨人にやられちまうってことか？  
>  I will probably end up eaten by other 巨人 if I bungle it and transform into
> a weak 巨人

鑑みる **に** is explained in this answer:

And ライナーでさえここで休まざるを得ない現状を鑑みるに apparently connects with the following line,
which is why context is important here.
