A) it would improve chances since it would protect inner, Terrestrial-like planets from impacts
B) it would improve chances slightly since some of the Terrestrial planets may become moons of the Jovian planet

The inward migration of a Jovian-like planet in an extrasolar planetary system would greatly decrease the probability of Life appearing since it would disrupt the orbits of the inner, Terrestrial-like planets. This would lead to major changes in the conditions necessary for life to exist, such as temperature and the availability of water. Additionally, any moons that may have formed around the Jovian planet would likely be inhospitable to life due to extreme radiation and temperature conditions.
