Does the principle of considering the special needs of people conflict with the principle of equal treatment for all?

No, the principle of considering the special needs of people does not conflict with the principle of equal treatment for all.

a. Sometimes even non-discrimination between people and rewarding them proportionately to their efforts might not be enough to ensure equality and social Justice. So, taking in account the special needs of people and treating them differently provides social justice.

Example: for a disabled person having seats reserved in bus/train, is providing social justice and does not hinders Equality for all.

b. People with special needs are given special treatment to facilitate their participation in this running society.

c. The senior citizens, women, children and disabled are given special treatment due to their special needs.
