The lust that Caliban has and the love that Prospero has for Prospero's daughter Miranda is another similarity that the two possess. However, because of Caliban's attempted rape of Miranda, Prospero feels that he has the right to make Caliban do what he says and to be his slave. .
Caliban hated Prospero after he tried to rape Miranda this shows his evil through the relationship between these two. This love that the two have for Miranda not only represents their similar interests, but also the fact that they are both capable of love. Both of these characters have been through extremely difficult situations. From Prospero being betrayed by his brother and Caliban never having a real family and being indentured into servitude, both of these characters represent the effects that hard times can have on one's character and well-being. However, Prospero does in the end forgive his brother and Caliban for their wrongdoings. This shows that underneath all of the resentment and anger that Prospero has, there is still a sound and forgiving man who is willing to do the right thing in order to provide the best life and example for his daughter. Caliban is a very hurt being who eventually is driven so mad by his own rage that he conspires with the two drunkards Stephano and Trinculo in order to enact a rebellion upon Prospero and had planned to kill his master Prospero for all the things he has done bad to Caliban. This could be seen as a reflection of Prospero's hate for his brother and his action of bringing about the storm so that his brother will be washed up onto the island and have to face him. The issues that both Caliban and Prospero have with the individual who drives them to blind rage are issues that they both eventually come to let go and even forgive the other party involved. This shows that both characters are able to go through a period of unhealthy rage and even plot against the other person, but can come out on the other side of things and let themselves release this anger so that they may once again prosper.
