In my eyes lobha, dosa and moha have no force or power in themselves which can increase the illusion. The ego-illusion can exist just as well in positive behaviour, for example "I
help people". There is still the concept (or illusion) that there is a static, unchanging "I" which acts and recieves the consequences of any action. In reality everything is changing and hence impermanent. So although there is a sensation of "I", with further investigation it may turn out that there is no seperate "I", really there is just movement, be it lobha, dosa or any other phenomena.
The reason we are told to watch lobha, dosa and moha, in my opinion, is so that we can reduce and eliminate them from our mind. The reason being is that the less negativity, regret and worry there is in our mind then the more our mind will free us from ignorance and lead us to nibbana through the jhanas (states of meditation).
