Othello is a conflicting character due to the fact that he is an insider because of his military job, however he is an outsider due to his race. this is shown when Othello says that 'boasting is an honour, i shall provogulate'. by this, Othello means that he is as noble as Desdemona, his wife, in different ways. This conflicts the points when Othello is referred to as 'the moor' which instead shoiws Othello to be an outsider due to his race.
The fact that Othello and Iago are stood 'outside of the Saggitary' which helps to set up the tragedy as it enforces the idea that Othello is doomed from the start. this is because the 'Saggitary' refers to a sculpture of a half archer half man which has negative and dangerous connotations.
