Questions about multiple particles 「は」and 「を」and interpunct in this sentence


Here is the sentence.

左ジャブと右ストレートのワンツーを覚えた矢吹丈は、力石徹 **を** 殴り倒すことだけ **を**
目的に地獄の中で生き抜くのですが、改めて読んでみて、これほど面白く・感動的な物語り **は** そう滅多に **は** ないと、僕は思いました。

Note: This sentence is written vertically.

  1. For the second bold 「を」, I am not sure which object and verb relate to it. If the verb is「改めて」, then what is the object?

  2. For the both bold 「は」, does it still have the same meaning and be grammatically correct if I remove them both?

  3. For the interpunct between the word 「面白く」and 「感動的」, what is the purpose to put it in the place? 




  1. を in を目的に indicate a object for 目的, it is 力石徹を殴り倒すことだけ in this case.

  2. I think first and second は are a topic maker and third one is emphasis. You can remove the emphasis は and first は but you had better not to remove second は.

  3. I don't know the reason. I think it is no problem it is comma.
