Which character is most admirable in from le morte d'arthur?

I think Sir Gareth is most admirable. He suffers the abusive tongue of Linet as they journey from Camelot to her sister's castle. And in spite of her insults, Garerht fights and defeats knights and thieves left and right. In fact, he says her insults only drove him to fight harder to prove himeslf. And in the rest of the Morte d'Arthur, Gareth always is on the side of chivalry. He doesn't betray his lord's trust like Lancelot did. Gareth doesn't even want to take sides when lancelot and Guinevere's affair is exposed. When she is condemened to burn at the stake, Gareth serves as a guard against his own wishes and only under orders.
