In Kafka's "The Metamorphosis," the speaker expresses deep distress over a troubling situation. The phrase "We can't carry on like this" signals a recognition that the current state of affairs is unbearable. There’s an urgent need to address the problem at hand, which is symbolized by the "monster" that the speaker refers to. This monster represents a significant change or burden affecting the family dynamic.

The speaker's desire to not call the monster their brother suggests a profound sense of alienation and rejection towards a once-familiar relationship. This highlights the struggle of coping with drastic changes in identity and the anxiety surrounding the loss of connection with loved ones. The call to "try and get rid of it" reflects a desperate hope for resolution and return to normalcy, emphasizing the emotional turmoil and complexity of familial bonds in the face of transformation.
