According to the passage, how were Jansson and her characters similar?

Tove Jansson's concern of the downtrodden, compassion with the poorest is shown and extended to her characters as if she wanted to speak to the whole world through those characters to bring about necessary changes. Jansson's ability to stretch her concerns onto distinctly different characters, finding new shades of her familiar ground. Jansson's writing, across nearly all of her prose, is attentively turned towards isolated work and companionship - the emotional intricacies of people who battle over and for these things, whether by themselves or with another. These struggles are quiet ones, with tempers turned inward and rarely lost, but in her keen perceptions of the characters she creates, all the tensions of relationships - of the pulls towards and away, of the need to be alone and the need to have someone, of mutual desires and desires that conflict - are put before the reader. Jansson is a sensitive writer; there is obvious compassion for the people of these stories. But in this sensitivity, there is fierceness. No one will be spared the harshness of the world or the cruelty others, or nature, though her prose quietly sides with those most wounded.
