Deadliness of the virus is just a side effect of its fast spread - the major part of the spread is replication which damages the host. The virus is an optimization problem - replicate and spread as fast as you can as long as the associated host damage and deaths result in the spread decrease smaller than the gain from the replication intensity increase causing that damage and deaths.
