As this site has long argued, the real motivation for those looking to promote illegal immigration has nothing to do with compassion. Those promoting illegal immigration are after political power, and the attainment of their own political agenda.
They seek to give these illegal immigrants the right to vote in domestic elections, thus overcoming the will of the citizens. Ultimately, they seek to use this imported voting block to attack the national sovereignty of the host nation, in order to merge 10 nations into one mega-state — and bring about the rise of the anti-Christ (aka, the secular Jewish moschiach).
